Speed tips
🚗
Driving: 100 km/h = 62 mph. 60 mph = 97 km/h. Know the limits when driving internationally.
🏃
Running: 10 km/h = 6.2 mph = 6:00 min/km pace. Convert your pace between metric and imperial.
✈️
Aviation uses knots (nautical miles/hour). 1 knot = 1.852 km/h = 1.151 mph.
💡
Mach 1 = 1235 km/h (speed of sound at sea level). The converter handles supersonic speeds too.
