Kilometers per hour to Meters per second
Type a value in km/h and get m/s instantly: 1 km/h = 0.2778 m/s
1 km/h = 0.2778 m/s
⇄ Meter per second → Kilometer per hourThe conversion between kilometers per hour (km/h) and meters per second (m/s) is fixed: 1 km/h = 0.2778 m/s and 1 m/s = 3.6 km/h. To convert km/h to m/s, multiply by 0.2778; to go the other way, multiply by 3.6 (or divide by 0.2778). For example, 36 km/h = 10 m/s and 100 km/h = 27.778 m/s.
Enter any value in the converter above; the result updates as you type. You will also find a ready-made table for common values, the formula, and a link to the reverse conversion (meters per second to kilometers per hour).
Multiply m/s by 3.6 to get km/h, divide km/h by 3.6 to get m/s (1 hour = 3,600 s, 1 km = 1,000 m). Weather services often give wind in m/s; the speed of sound is about 343 m/s ≈ 1,235 km/h.
