Convert Meters/second to Kilometers/hour (m/s to km/h)
1 m/s = 3.6 km/h. Convert meters/second to kilometers/hour with the exact factor, a common-values table and a free converter.
Conversion factor
km/h = m/s × 3.6
1 m/s = 3.6 km/h
Multiply by 3.6 km/h to go from meters/second to kilometers/hour, or divide by it to come back. The factor and every value below are computed by the same converter that runs at /convert, so this page and the tool cannot disagree.
m/s to km/h table
| Meters/second (m/s) | Kilometers/hour (km/h) |
|---|---|
| 1 m/s | 3.6 km/h |
| 2 m/s | 7.2 km/h |
| 5 m/s | 18 km/h |
| 10 m/s | 36 km/h |
| 20 m/s | 72 km/h |
| 50 m/s | 180 km/h |
| 100 m/s | 360 km/h |
Every figure is computed at build time by the site’s own converter from the speed unit registry. For a value that is not listed, put it into the interactive converter.
Frequently asked questions
How many kilometers/hour are in one meter/second?
One meter/second is 3.6 km/h, so 100 m/s is 360 km/h.
What is the formula to convert meters/second to kilometers/hour?
km/h = m/s × 3.6. Multiply the value in meters/second by 3.6 to get kilometers/hour.
How do I convert kilometers/hour back to meters/second?
m/s = km/h × 0.277777778, so 1 km/h is 0.277777778 m/s. The km/h to m/s page carries the same table in that direction.
