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 mile ≈ 1.6 km. Mental trick: add 60% to the mile figure.
  • A running mile in 4 minutes is an elite pace; a recreational runner covers it in 8–10 minutes.
  • US cars show mph only. Check the speedometer scale before assuming the units.

Avoid these

  • Confusing statute miles (1.609 km) with nautical miles (1.852 km) — a 15% gap.
  • Reading a US speedometer as km/h — 70 mph is 112 km/h, not 70.
  • Using 1.5 or 1.6 for quick conversions when precision matters — use 1.609 for engineering or legal documents.
