km/h to m/s Converter - Kilometer per Hour to Meter per Second
Kilometer per Hour (km/h) to Meter per Second (m/s)
Direct answer
1 km/h = 0.277778 m/s
m/s = km/h × 0.277778
Converter
Conversion formula
m/s = km/h × 0.277778
km/h = m/s × 3.59999712
Example: 10 km/h = 10 × 0.277778 = 2.77778 m/s.

Conversion factor from kilometer per hour to meter per second
The conversion factor between kilometer per hour and meter per second is a fixed ratio derived from their definitions. Kilometer per hour measures distance in kilometers over time in hours, while meter per second measures distance in meters over time in seconds.
Definition
Kilometer per hour (km/h) is a unit of speed where 1 kilometer is traveled in one hour. Meter per second (m/s) is a unit of speed where 1 meter is traveled in one second.
Principle
To convert km/h to m/s, multiply by the factor 0.277778. To convert m/s to km/h, multiply by the factor 3.59999712.
Assumptions
- The conversion factor is defined as 0.277778 for km/h to m/s.
- The reverse conversion factor is defined as 3.59999712 for m/s to km/h.
Cautions
- Results should be rounded to the precision required by the calculation.
- The conversion factor 0.277778 is a rounded value; using the exact defined ratio is preferred for high-precision work.
