To convert meters to miles (m to mi), multiply by 0.00062137. 1 meter equals 0.00062137 mi, about 1.4 times as much as a tennis racket.

Definition: The base unit of length in the metric system - every other metric length (km, cm, mm) is just meters multiplied or divided by a power of ten.
History: Born out of the French Revolution's push to replace a chaotic patchwork of local, often royally-defined units with something rational and universal. In 1793, French scientists defined the meter as one ten-millionth of the distance from the North Pole to the Equator, measured along the meridian running through Paris - they actually sent surveyors out to physically measure the distance between Dunkirk and Barcelona to calculate it, a project that took years longer than planned. Today the meter is defined by something far more precise and impossible to argue with: the distance light travels in a tiny, fixed fraction of a second.
Current use: The foundation of virtually every length measurement outside the US - room dimensions, building heights, and race distances (measured in km) all build on it.
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 0.000621371, 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 1,609 instead. That is the number worth remembering, because 1,609 meters make one mile exactly.
Going the other way, one mile is 1,609 m, 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 meters is about 1.55 mi.
