The official distance became 300 meters, but many competitions continued to be in yards because the tracks were still marked for that distance. Hurdle heights also have undergone a period of evolution. Until 1984, boys ran over low hurdles 30" in height. When girls were introduced to the event around 1981, they ran the same height as the boys ...

From 1630 to 1718 a millia was 5,564 feet (1,696 metres), making a geographical league of four millias equal 22,256 feet (6,784 m or 3.663 modern nautical miles). But from 1718 through the 1830s the millia was defined as the equivalent of just over 5,210 feet, giving a shorter geographical league of just over 20,842 feet (6,353 m or 3.430 ...
It is widely accepted within interdisciplinary circles that for a standard rifle firing full-powered cartridges (e.g. .308 Winchester), "long range" means the target is more than 600 m (660 yd) away, [citation needed], while "extreme long range" is generally accepted as when the target distance is more than 1,000 m (1,100 yd) away from the shooter.
The rod, perch, or pole (sometimes also lug) is a surveyor's tool [1] and unit of length of various historical definitions. In British imperial and US customary units, it is defined as 16 + 1 ⁄ 2 feet, equal to exactly 1 ⁄ 320 of a mile, or 5 + 1 ⁄ 2 yards (a quarter of a surveyor's chain), and is exactly 5.0292 meters.

The 1500 m, however, is the most common distance run at the college and international levels. The final leg of a distance medley relay is 1600 metres. An accurate way to run an actual mile on a metric track is to run the additional 9.344 meters before starting the first marked 400-meter lap.
After that, the IAAF stopped ratifying records in the 200 metres low hurdles and it became far less common. United States high schools ran a shortened version of the race, the 180 yard low hurdles, until 1974, when most states and the NFHS converted to running the 330 yard low hurdles that with metrification evolved into the 300 meter ...
