Throughout history many units of length named ''mile'' have been used, with widely differing definitions, originating with the ] mile of approximately 1479 m. A Roman mile consisted of 1000 "double steps", or two strides by a Roman soldier. The Latin term for each such double stride is a ''passus'' having a length of 5 Roman feet or approximately 4.83 English feet. The word ''mile'' itself has been derived from the words ''mille passus'' (plural ''millia passuum''), a thousand paces. Along the roads built by the Romans throughout ], it was common to erect a stone every mile to announce the distance to Rome, the so-called milestones. The noun ''milliarium'' (plural ''milliaria''), designating a milestone, was also used as a figurative alternative for ''mile''. | ||

=== Old English or Anglo Saxon units derived from the Greeks and Romans === | |||
: The Virgate - "An old English unit of area" is actually Roman in origin | |||
: equal to one quarter of a hide = 1.25 yerdis = 17.5 acres | |||
: The amount of land needed to support a person. | |||
: The hide is at its root a German word for household, but | |||
: the hide is a Roman derived unit | |||
: We are told that in the Saxon counties of southern England, | |||
: it referred to the land sufficient to support one family, | |||
: which equaled what the family plowed in a year. | |||
: We are told that depending on the fertility of the land, the hide varied | |||
: from as little as 60 to as many as 240 acres, half a knights fee | |||
: but it was typically between 80 and 120 acres, 1/4 knights fee | |||
: Its actually 60 modern English, and 70 old Roman acres | |||
: We are told that the bovate is 1/8 of a carucate, | |||
: which also appears in the Domesday Book originated as a Danish measure | |||
: and it is found in the northeastern English counties | |||
: constituting the Danelaw. | |||
: Lets allow a carucata or carucate, like | |||
: 1 hide, is approximately 120 acres and | |||
: like the bovate was found in the Danish counties. | |||
: Lets allow A Plowland or plowgate is equal to a carucate or | |||
: an area eight oxen can plow | |||
: sufficient for a free family to support itself; | |||
: its origins precede 1100. (see definitions of Sumerian areas) | |||
: We are told the plowland compares with the knight’s fee | |||
: which we have established originates with the Milos | |||
: which was a larger area sufficient to support a knight’s family | |||
: (perhaps to allow pasture for animal husbandry). | |||
: Sulung is a Kentish term for two hides. | |||
: Its 120 modern English, 140 Roman acres | |||
: A yoke in Kent is 1/4 of a sulung. | |||
: A virgate is a rod in linear measure and 1/4 of a hide | |||
: (or 30 acres) used as a measure of area in Saxon counties. | |||
: 30 acres is 1/4 sulong | |||
: We have the Arpent AS a unit of length =~ 191.8 feet and | |||

=== Longer Discussion === | |||
Stadios | |||
: The Greek root stadios means "to have standing" | |||
: "to have standing" means to be a landowner. | |||
: Land measures including both | |||
: length and area are based on the size of fields | |||
: The base units are the remen, pace, yard, orguia, | |||
: fathom, rod, cord, perche and furlong. | |||
: Body measures fingers, thumbs, palms, hands, fists, feet, forearms | |||
: are related and worked into the system as multiples of the foot. | |||
: Different classes of citizen and occupation are apportioned | |||
: different amounts of land by the community | |||
=== Ancient Degree Based Stadia Standards of Measure === | |||
: Ancient stadia measures were always divisions of the degree | |||
: Systemized standards of measure derived from this common standard | |||
: Mesopotamia used 600 sos of 180 m = 108 km | |||
: Egypt used 10 itrw = 700 "3ht or fields" (of 3 kht of 100 royal cubits) = 110.25 km | |||
: Persia used 20 parasangs of 30(furlongs = 185 m) = 111 km | |||
: Phoenicia used 500 stadions (of 750 feet = 185 m) = 111 km | |||
: Ptolomy and Marinus of Tyre measured in the Persian/Phoenician stadia | |||
: Eratosthenes measured in the 700 3ht of Egypt. | |||
: The Greeks used 600 stadions (of 600 pous of 308.4 mm) = 111 km | |||
: The Romans used 600 stadiums of 625 pes (of 296 mm = 111 km | |||
: All of those are accurate divisions of a degree as defined by Ptolomy | |||
: Ancient Europe used the same standards because it did business with the same people | |||
: The credit for the first systemized collection and standardization | |||
: probably goes to the empire builders of Mesopotamia and Egypt | |||
: but the international commerce of the people who benefited | |||
: by those great empires, the Greeks and Persians and the Romans | |||
: who followed them is what really required the system | |||
: be standardized over such vast areas. | |||
: The important thing to recognize is that you can | |||
: identify the original source as Mesopotamian or Egyptian | |||
: depending on whether the system is sexigesimal | |||
: or septenary and whether the divisions are by palms or feet or both. | |||
=== Egyptian Itrw and Atur === | |||
: The Itrw is an hour of travel on the river = 21,000 royal cubits | |||
: The Atur is an hour of march on the land = 21,000 royal cubits | |||
: The minute of march is a unit of 1 minutes travel = 350 royal cubits | |||
: 21,000 royal cubits = 36,085 English feet = 6.83 modern miles | |||
: It equaled 7.22 miles prior to the time of Queen Elizabeth | |||
: That was 11 km or 7.43 Roman milliare. | |||
: 75 Roman milliare are a pretty good value for a degree | |||
: The Egyptian value for 10 itrw is a little less accurate | |||
: and that probably explains the correction. | |||
=== The Egyptian Minute of March as Stadion, Stadium, Furlong === | |||
: In Egypt the minute of march was 350 royal cubits long and | |||
: an hour of march or itrw was 21,000 royal cubits long. | |||
: The Greeks tell us they noted their | |||
: measures of 6 plethrons and 8 stadions, | |||
: were both the equivalent of the Apothem slant side of the Great Pyramid. | |||
: The modern nautical mile was ten times the length of that Apothem. | |||
: Using unit measures like the Stadion, Stadium and Furlong, which | |||
: were originally used to lay out fields and gradually became | |||
: defined as areas like the Aroura or thousand square royal cubits, | |||
: the empire builders measured out their roads. | |||
: The Greek Milos was originally 8 stadions or | |||
: 600 Greek pous x 8 = 4800 pous | |||
: The Pous came in long short and median variations | |||
: so depending on which one you used the number of pous | |||
: would vary even as the length of the stadion and | |||
: Milos remained the same. | |||
: 600 Attic pous were equal to 625 Ionian pous but | |||
: both stadions were 185 meters long | |||
: The Romans standard pes was the Ionian pous of 296 mm so | |||
: they made their stadium of 185 meters | |||
: egual to 625 pes or 1000 passus and | |||
: that made their Milliare 5000 pes | |||
: What makes that a great system for empire builders is that | |||
: the passus is now a measure of the pace at which the army moves. | |||
: If such standards of measure are well suited to | |||
: controlling the movements of armies with milestones | |||
: related to how much distance can be covered in a set period of time | |||
: they are equally servicable to the needs of commerce. | |||
: Just as the farmer can use the stone walls that border his field | |||
: to help him restablish its boundaries after a flood, | |||
: the community can establish its bounds in terms of | |||
: how much land it needs to irrigate to sustain its population and | |||
: the lugal or narmr (chief farmer)can determine | |||
: how many men he needs to dig the irrigation system and | |||
: how much land to alot to each oinkos, gene and phratre | |||
: in return for their service. Its all very feudal. | |||
: The city state is based on a market or agora that | |||
: serves a number of communities which are | |||
: spaced about as far apart as a man can walk in a day | |||
: driving a team of oxen pulling a cart. | |||
: When it takes more days to get the goods to market | |||
: than it takes for the crops to spoil you need a new market. | |||
=== Vestigal Remnant of ther English Cubit on the Stanley Tape Measure === | |||
: Pull out your standard everyday run of the mill Stanly tape measure and | |||
: you should see a diamond at 19.2" | |||
: That is the ancient ordinary English cubit and its | |||
: the basis of the English League of three modern miles or | |||
: anciently in the time when a mile was 8 furlongs of 600 feet, | |||
: 14,400 ft and 9,000 diamonds. | |||
=== Milliare based Roman area === | |||
: 1 square foot, pes quatratus ≈ 875 cm² | |||
: 1 square perch, scripulum = 1 pertica quadrata ≈ 8.75 m² | |||
: 1 aune of furrows, actus minimus = 1/30 actus quadratus ≈ 42 m² | |||

a table of | |||
the European measures listed by Ogilvy, Cowell Speed and others | |||
such as George Buchanan's Rerum Scoticarum Historia (1582), which deals with the geography of the British Isles and of Scotland in particular. | |||
from just before Queen Elizabeth changed them by statute in 1593 | |||
to the present day. | |||
On old maps the scales are generally given in Milliaria which means the standard being used is Roman miles. Even is some areas of the United States, which were settled prior to 1593 you can find property defined by the older set of standards so that fields were laid out to a furlong which was 1/8 of a Myle of 5000 fote. | |||
On Mercators map you can see the Roman Milliare is divided into 8 furlongs | |||
"So far as I have tryed be cownt or experience I do find a common myle of our cowntrey to hold of ellns sixteen hundreth, sumtyms they ar longer, sumtyms they ar shorter, and very rudelie ar they cownted but I do hold this may be a just proportion to stand for all, being measured in a right lyne." | |||
"I do find that 50 of our myles agreeth best of all to 60 Italian miles or a degree, wherupon I have followed out all the latituds of Scotland." | |||
Cowell speaking of Scotland. | |||
I read that to mean that a degree of latitude is taken as | |||
60 miles in Italy, but 50 miles in Scotland and thus is related | |||
to a Roman Mile of which there are 75 to a degree as 50/75 | |||
or in other words 1600 ellns = 3333.33 Roman feet of 296 mm | |||
we can now compare | |||
1/2 elln 616.67 mm = Greek pous of 308.4 mm | |||
1/2 aln or alnar = 1 fot = 296 mm = 1 Roman pes | |||
At the moment I have huge collections of such ancient datems | |||
so I thought putting them in a table might be useful. | |||
The idea is to see if its possible to track where | |||
the standards of measure in the modern west have their roots. | |||
As an architect I would describe this as a little like | |||
trying to preserve an ancient building scheduled for demolition | |||
to make way for a modern high rise. | |||

The length of Scotland upon the East coast from Dungisbie head to Barwick upon a straight lyne of north and south is 160 myles. but upon the west syd it is much more to Sulway firth and Eskmouth for theis ly upon south westward from Barwick | |||
Latitude of Dungisbie head according to Mr Timothie Ponts his setting down is 58 Gr. 32 M. | |||
the nordermost poynt of all the Orkney Yles according to him is 59 Gr 24 M. | |||

Edinburgh is set be him in his mappe of Lothian under 55 Gr 46 m. According to his reconing in that mappe - 15 Scottish myles do answer to 20 minuts of Latitude so that therby 45 of our myles do mak a degree, but it is falss, for be his cownt Dungsbie head sould fal to be 58 Gr. 51 m. which yit in his mappe of Orkney he maketh to be onlie 58 Gr. 32 so that the difference is 19 m. | |||

Now comparing the latitude of placis in our cowntrey, be sum few observations of utheris, I do find a sensible difference among them, and Mr Timothie in his mappes of Lothian and Orkney doth not agrie with himself, wherfor casting all that asyd, in Latitude I have followed Cambden and the English as most accurat, who place Berwick under 55 Gr. 48 M and I do find that 50 of our myles agreeth best of all to 60 Italian miles or a degree, wherupon I have followed out all the latituds of Scotland. | |||

A mile is any of several units of distance, or, in physics terminology, of length. Today, one mile (often called "statute mile") is equal to about 1609 m on land and one nautical mile to exactly 1852 m at sea and in the air. See below for the details. Abbreviations for mile are "mi" in the U.S., and "ml" and "m" in the UK.
There are various miles, however:
- The statute mile, or more specifically
- The international mile is the one typically meant when the word mile is used without qualification. It is defined to be precisely 1760 international yards (by definition, 0.9144 m each); it is therefore exactly 1609.344 m. It is used in the United States and the United Kingdom as part of the Imperial system of units. The international mile is equivalent to 8 furlongs, or 80 chains, or 5280 international feet.
- The U.S. survey mile is precisely equal to 5280 U.S. survey feet or 6336/3937 km or, approximately 1609.347 m. One international mile is precisely equal to 0.999 998 survey mile. The survey mile is used by the United States Public Land Survey System.
- The statute mile simply means a mile of 5280 feet, without specifying which foot is used. The term is therefore ambiguous.
- The international nautical mile is defined to be exactly 1852 m. It is used universally for aviation, naval and maritime purposes and originated from the geographical mile.
- In Norway and Sweden, a distance of 10 km is most commonly referred to as a mile, see mil.
History
Throughout history many units of length named mile have been used, with widely differing definitions, originating with the Roman mile of approximately 1479 m. A Roman mile consisted of 1000 "double steps", or two strides by a Roman soldier. The Latin term for each such double stride is a passus having a length of 5 Roman feet or approximately 4.83 English feet. The word mile itself has been derived from the words mille passus (plural millia passuum), a thousand paces. Along the roads built by the Romans throughout Europe, it was common to erect a stone every mile to announce the distance to Rome, the so-called milestones. The noun milliarium (plural milliaria), designating a milestone, was also used as a figurative alternative for mile.
In navigation, the geographical mile was commonly used, defined as 1 minute of arc along the Earth's equator, approximately equal to 1855 m.
The name statute mile goes back to Queen Elizabeth I of England who redefined the mile from 5000 feet to 8 furlongs (5280 feet) by statute in 1593.
When the international mile became legal in mid-1959, the survey mile was retained for measurements derived from U.S. cadastral surveys.
In Denmark and most of Germany the mile in the 19th century was an approximately 7.5 km geographical mile (determined by 4 minutes of arc) specified by Ole Rømer. In parts of Germany there also existed an exact 7.5 km "metric mile" variant, but it mostly went out of use at the beginning of the 20th century. The Ole Rømer mile was for a long time used as a sea mile in Scandinavia, but was in the middle of the 20th century replaced by the international nautical mile (which corresponds to 1 minute of arc). The international nautical mile is still often referred to by traditionalist Scandinavians as a quarter mile. In Norway and Sweden, a mile in daily speech refers to a traditional unit that is still very commonly used, but now defined as 10 km, see mil.
In Ireland the Irish mile of 2240 yards (about 2048.3 m) was used legally until 1826, and by some reports survived until the conversion to the metre as the unit measurement for distance, in early January 2005.
The 'Collins English Dictionary' defines a sea mile as 1828.8 m (6000 feet), being "an Imperial unit of length, formerly used in navigation".
Others miles are:
- Russian verst
- 1066.8 m (exactly 3500 feet = ca. 1168 yards) of 500 sazhen
- Scotch mile
- 1814.2 m (1984 yards) of 320 falls
- Austrian Meile
- 7585.9 m (8296 yards) of 240 Ruten (rods) or 400 Klafter (fathoms)
