How do I convert miles to yards?
Multiply by 1,760. It's exact, and it's the one imperial length figure most people half-remember.
3 miles is 5,280 yards – the same 5,280 that's the number of feet in one mile, which catches everyone out at least once.
A marathon is 26 miles 385 yards, or 46,145 yards in all. The odd 385 dates from the 1908 London Olympics, when the course was stretched so the race could finish in front of the royal box.
What is a mile?
A mile is an imperial and US unit of length, exactly 1,609.344 meters. The word comes from the Latin mille passus, 'a thousand paces', where a pace was two steps of a marching legionary.
A mile is equivalent to 1760yds or 5280ft.
Road distances in the US and UK are signed in miles, while nearly every other country uses kilometers. Aviation and shipping use the nautical mile instead, which is a different length (1,852 meters).
What is a yard?
A yard is 3 feet or 36 inches. In the US you mostly see it on football fields, which run 100 yards between the goal lines, and in the UK short road distances are still signed in yards.
The yard is traditionally the distance from the nose of King Henry I of England to the thumb of his outstretched arm, though its length varied from place to place for centuries. It was only fixed internationally in 1959, at exactly 0.9144 meters.
Nearly every other country uses the meter instead. In the US, bulk soil and mulch are still sold by the cubic yard, which is 27 cubic feet.
