How to Convert KPH to MPH
1 km/h = 0.621 mph. Divide km/h by 1.60934 (or multiply by 0.621) to get mph. So 100 km/h ÷ 1.60934 = 62.14 mph. Quick mental: multiply by 5/8 or by 0.625. 100 × 5/8 = 62.5 mph (within 0.6% of exact 62.14).
Useful when interpreting European speed limits in UK/US terms. A 130 km/h French motorway limit = 81 mph (faster than UK/US 70 mph). A 50 km/h urban limit = 31 mph. A 30 km/h school zone = 19 mph. The 5/8 rule (multiply by 5/8) is fast enough to do mentally.
