Kilometers per Hour to Meters per Second Converter
1 kilometer per hour = 0.2777777778 m/s. Enter any value to convert kilometers per hour (km/h) to meters per second (m/s), or use the table below for common values.
Formula
m/s = km/h × 0.2777777778
Example: 10 km/h = 2.777777778 m/s. To convert the other way, use km/h = m/s × 3.6.
Quick mental estimate: multiply by about 0.28.

Frequently asked questions
How do I convert kilometers per hour to meters per second?
Use the formula m/s = km/h × 0.2777777778. For example, 10 km/h = 2.777777778 m/s.
What is 1 kilometer per hour in meters per second?
1 km/h = 0.2777777778 m/s.
How do I convert meters per second back to kilometers per hour?
Use km/h = m/s × 3.6. 1 m/s = 3.6 km/h.
