How to Convert Kilometres to Miles
1 km = 0.62137 miles. Divide kilometres by 1.60934 (or multiply by 0.62137) to get miles. So 100 km × 0.62 = 62 miles. Quick mental approximation: divide by 1.6 (or multiply by 0.625, which is 5/8). 80 km × 5/8 = 50 miles, accurate to within 0.5%.
The conversion comes up most often when interpreting European driving distances or speed limits in American/UK terms. A 100 km/h Autobahn limit is 62 mph. A 200 km route is 124 miles. Olympic 5000 m run = 5 km = 3.1 miles. The 5/8 mental shortcut works well for road-trip planning.
