To convert yards to miles (yd to mi), multiply by 0.00056818. 1 yard equals 0.00056818 mi, about 1.3 times as much as a tennis racket.

Definition: 3 feet, or exactly 0.9144 meters.
History: Popular legend credits King Henry I of England, who supposedly declared in the 12th century that a yard was the exact distance from the tip of his nose to his outstretched thumb - a good story, though historians note the yard likely existed informally before him and he simply made it official. Either way, by 1959 the same six-country agreement that fixed the foot and inch also locked the yard to its current, precise metric equivalent.
Current use: Fabric and carpet measurements, American football fields, and golf distances are still commonly given in yards.
Definition: A mile is 5,280 feet, or exactly 1,609.344 meters.
History: It started as the Roman "mille passus" - literally a thousand paces, where a pace was a Roman soldier's double-step, about 5 Roman feet. That put the original Roman mile at 5,000 feet. Centuries later, English farmers were measuring land in furlongs (660 feet, the length of a furrow before an ox needed a rest), and in 1593 Queen Elizabeth I's Parliament decided a mile should equal exactly 8 furlongs - bumping the mile from 5,000 feet to 5,280, the number that's stuck ever since.
Current use: The US, UK, and a handful of other countries still measure road distances in miles. Aviation and shipping use a different mile entirely - the nautical mile, based on the Earth's circumference, not Roman soldiers' footsteps.
The factor is 0.000568182, which is derived rather than defined, so any decimal you see has been rounded somewhere.
There is no tidy multiplier here, so work the other way: divide by 1,760 instead. That is the number worth remembering, because 1,760 yards make one mile exactly.
Going the other way, one mile is 1,760 yd, which is usually the easier direction to work in. Because the forward factor is small, watch the decimal place rather than the digits: a factor-of-ten slip is the common error, not a rounding one.
To anchor the scale: 2,500 yards is about 1.42 mi.
