02Conversion factors

All conversions go through metres per second:
1 km/h = 1 ÷ 3.6 m/s
1 mph  = 0.44704 m/s
1 ft/s = 0.3048 m/s
1 knot = 1 nautical mile per hour = 1,852 ÷ 3,600 m/s

03Examples

60 mph = 96.56 km/h.

100 km/h = 62.14 mph.

20 knots = 23.02 mph.

04Frequently asked questions

What is a knot?

One nautical mile per hour. A nautical mile is exactly 1,852 metres, so a knot is about 1.15 mph. Knots are used at sea and in aviation.

How do I convert mph to km/h in my head?

Multiply by 1.6. For km/h to mph, multiply by 0.6. Both are within about 1%.

Is pace (minutes per mile) supported?

Not yet. Pace is the inverse of speed: 60 ÷ mph gives minutes per mile.
