A unit of distance called a mile was first used by the Romans and originally denoted a distance of 1,000 (double) steps (mille passuum in Latin), which amounted, at approximately 29 inches (0.74 m) per (single) step, to 1,618 yards (1,480 m), or 5,000 Roman feet, per mile.\n\nA statute of the English parliament during the reign of Elizabeth I established the statute mile as eight furlongs or 1,760 yards; that is, 5,280 feet or 63,360 inches\n\nThe U.S. survey mile is based on an inch defined by 1 metre = 39.37 inches exactly. It is equal to 5,280 U.S. survey feet, 6,336/3,937 km or approximately 1,609.347 metres\n\nGood luck

for measuring the length of things though each gives you a different unit.

England....they predate the metric system, for example a "foot" is roughly the length of an adult male's foot.\nNot sure why we don't use the metric system.  There was a big push to switch when I was in elementary school, but it never happened.

umm, none.  meters is a linear measurement and acres is a measurement of area.   That's like asking how many gallons are in a dollar

If it's outside the U.S.  or in the U.S. and it was built within the last 25 years or so, it is probably 400 meters.\n\nThey haven't been building 440 yd tracks in years.\n\nOne way to tell is to look at the starting marks for the 400 meters. If it is the same place as the finish line, then it's a 400 meter track. If it is 2+ yards away from the starting line, then it's 440 yds.

To answer this, one must return to days before these were in common usage, when distances were measured in travel days, journeys, and the like.  It wasn't until much later in history that humans began to want and require more specific and detailed measurements than "over there," and "a far piece" could describe.  When those days did indeed dawn, we used such terms as yards, furlongs, miles, etc., and had specific measures for them, and as such would require a kind of reference for them as well.  \n\nEven today, we do not travel much in inches, we travel in mileage; the numbers would be too large and cumbersome for any useful meaning.  However, with the development of nanotechnology, particularly as it may impact medical procedures, there may come into common usage such terms as "inchage" and "millimeterage."

Maybe because early pitches had different sizes before there was a rule. So the rule stated pithces had to be 100 to 130 yards wide and 50 to 100 yards long because most pitches probably were in that range, and if a single measure had been allowed, say 120 x 75 yards, all other pitches wouldn't have any purpose and clubs would have to create new ones.

That was the old definition of a metre. It was later changed because somehow they determined it wasn't accurate (like the distance between those two points became ten million and two metres.) I believe the current definition of a metre is the distance light travels in 1/299792458 of a second, but I've also heard it defined in terms of a certain number of wavelengths of a krypton laser.

The trade unions (plumbers, pipefitters, electricians) in the US were against switching over to metric.  It would have been too costly for them.

Why aren't you Americans using metric yet?\nDrag yourself into last century already!
