Question
How many meters per second are in one kilometer per hour?
1 km/h equals approximately 0.277778 m/s (exactly 1000/3600).
1 km/h
≈ 0.277778 m/s
100 km/h
≈ 27.778 m/s
Formula
m/s = km/h ÷ 3.6
Explanation
There are 1000 meters in a kilometer and 3600 seconds in an hour, so divide by 3.6 to go from km/h to m/s.
Multiply m/s by 3.6 to get km/h.
Example: 100 km/h ≈ 27.778 m/s; 10 m/s = 36 km/h.
