Convert Kilometers/hour to Meters/second (km/h to m/s)
1 km/h = 0.277777778 m/s. Convert kilometers/hour to meters/second with the exact factor, a common-values table and a free converter.
Conversion factor
m/s = km/h × 0.277777778
1 km/h = 0.277777778 m/s
Multiply by 0.277777778 m/s to go from kilometers/hour to meters/second, 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.

Frequently asked questions
How many meters/second are in one kilometer/hour?
One kilometer/hour is 0.277777778 m/s, so 100 km/h is 27.7777778 m/s.
What is the formula to convert kilometers/hour to meters/second?
m/s = km/h × 0.277777778. Multiply the value in kilometers/hour by 0.277777778 to get meters/second.
How do I convert meters/second back to kilometers/hour?
km/h = m/s × 3.6, so 1 m/s is 3.6 km/h. The m/s to km/h page carries the same table in that direction.
