One meter per second equals exactly 3.6 kilometers per hour.
Multiply the speed in m/s by 3.6. For example, 8.7 m/s × 3.6 = 31.32 km/h.
There are 3,600 seconds in an hour and 1,000 meters in a kilometer. So 1 m/s = 3,600/1,000 = 3.6 km/h. This is an exact conversion.
The speed of sound in air at sea level is approximately 343 m/s or 1,234.8 km/h.
