km/h to m/s (Kilometers per Hour to Meters per Second)
1 kilometer per hour equals 0.27777778 meters per second — divide km/h by 3.6 (or multiply by 0.27777778) to convert. The factor is 1,000 meters spread across 3,600 seconds, which reduces to 1 ÷ 3.6.
The formula
Multiply the km/h value by 0.27777778 to get meters per second:
m/s = km/h × 0.27777778
For example, 36 km/h × 0.27777778 = 10 m/s. To reverse, multiply m/s by 3.6.

Where this conversion is used
Meters per second is the SI base unit for speed, so physics problems, engineering calculations, and scientific instruments almost always require it, while everyday vehicle speeds are quoted in km/h. Students solving motion equations and engineers processing sensor data both convert km/h to m/s constantly. The tidy divide-by-3.6 shortcut makes it easy to do mentally.
FAQ
How many m/s are in a km/h?
One km/h equals 0.27777778 m/s. Multiply the km/h figure by 0.27777778 — for example, 10 km/h = 2.7777778 m/s.
What is the formula to convert km/h to m/s?
Use m/s = km/h ÷ 3.6, equivalently km/h × 0.27777778. The tool applies this exact factor automatically.
How do I convert m/s back to km/h?
Multiply by 3.6. For instance, 10 m/s = 36 km/h.
Is the conversion exact?
Yes — 1 km/h is exactly 1 ÷ 3.6 m/s; 0.27777778 is that repeating decimal rounded to eight places.
