About the Speed Converter
Convert speeds between kilometres per hour, miles per hour, metres per second, feet per second and knots.
How to use the Speed Converter
- Enter the Value and select the Unit.
- Press Convert to see every equivalent speed.
Formula and method
Everything is converted through metres per second: 1 km/h = 0.27778 m/s, 1 mph = 0.44704 m/s, 1 knot = 0.514444 m/s.
| Unit | Equals |
|---|---|
| 1 m/s | 3.6 km/h |
| 1 mph | 1.609344 km/h |
| 1 knot | 1.852 km/h |
| 1 km/h | 0.621371 mph |
Worked example
100 km/h = 100 × 0.621371 = 62.14 mph = 27.78 m/s.
Road speeds. 100 km/h = about 62.1 mph. 60 mph is roughly 96.6 km/h. To get m/s from km/h, divide by 3.6.
When to use the Speed Converter
- Converting speed limits and vehicle speeds between km/h and mph.
- Working with wind speeds, flight speeds and running paces.
- Physics problems in metres per second.
Common mistakes to avoid
- Mixing knots (nautical miles per hour) and mph.
- Forgetting to convert hours to seconds when moving to m/s.
Tips
- To convert km/h to m/s, divide by 3.6.
- Knots are used in aviation and at sea.
