mi

The statute mile equals 1609.344 meters exactly since the 1959 international definition. It is the official road unit in the United States, United Kingdom and Myanmar. The name comes from the Latin "mille passuum" — one thousand Roman paces. The nautical mile (1852 m) is different and used only in marine and air navigation.

Real-world: London to Edinburgh is about 400 miles by road. A marathon is 26.22 miles. US highways typically post 65–75 mph speed limits.

Tips & common mistakes

Quick tips

  • 1 km ≈ 0.621 miles — a quick mental shortcut is to multiply km by 0.6 (or 5/8).
  • To convert km/h to m/s divide by 3.6. Useful in physics problems.
  • A kilometer takes a healthy adult about 10–12 minutes on foot or 3 minutes on a bicycle.

Avoid these

  • Reading a US speed-limit sign as km/h when it is actually mph — 70 mph is 112 km/h, not 70.
  • Using 1.5 instead of 1.609 when converting miles to km on long trips — the error compounds.
  • Confusing kilometer (distance) with kilogram (mass). Both abbreviated with "k" prefix but measure different things.
