One kilometre equals 0.621371 miles. To convert:
miles = km × 0.621371
A fast mental shortcut: multiply km by 0.6 (slightly underestimates). For a quick rough estimate, km × 5 ÷ 8 is very close.
- 100 km × 0.621 = 62.1 miles
- 400 km × 0.621 = 248.5 miles
- 1 km × 0.621 = 0.621 miles
- 500 km × 0.621 = 310.7 miles
Canadian road signs are in kilometres and speed limits are in km/h, but when driving into the US, signs switch to miles and mph immediately at the border. Cross-border driving apps, Google Maps set to US location, and American travel guides quote distances in miles. Converting is essential for planning road trips from Canada to the US.
