Use this page to convert kilometers per hour into meters per second. It is useful when everyday metric road or travel speeds need to be used in physics, engineering, weather, sports science, or sensor calculations.
Kilometers per hour is familiar for travel; meters per second is better for technical calculation.
The conversion factor is exact.
Meters per second makes speed compatible with formulas that use meters and seconds.
Kilometers per hour remains better for road signs, dashboards, and public travel speeds.
This conversion is common in sports science, vehicle testing, and engineering.
This page converts speed and does not separately convert distance or time.
Kilometers per hour is easy to understand for travel and road speed.
Meters per second is easier to use in calculations involving acceleration, force, distance over seconds, or sensor timing.
The conversion changes the same speed into the metric unit that fits technical work.
A vehicle speed of 72 km/h is exactly 20 m/s.
That form is easier to use in formulas that calculate stopping distance, motion, or time to cover meters.
Keep km/h for communication and m/s for calculation when both audiences matter.
3.6 km/h should equal exactly 1 m/s.
36 km/h should equal exactly 10 m/s.
If 1 km/h becomes 3.6 m/s, the conversion direction has been reversed.
Definition: Kilometers per hour measures how many kilometers are traveled in one hour.
History/Origin: Kilometers per hour is the common road and travel speed unit in most metric countries.
Current use: kph is used for road speeds, vehicle dashboards, travel estimates, cycling, running, weather, and public-facing metric speed.
Definition: Meters per second measures how many meters are traveled in one second.
History/Origin: Meters per second is used in physics, engineering, weather, sports science, simulations, and sensor-based speed measurement.
Current use: mps is used for physics, engineering, sensor data, wind speed, sports analysis, simulations, and technical calculations.

|---|---|
| 0.01 km/h | 0.002778 m/s |
| 0.1 km/h | 0.027778 m/s |
| 1 km/h | 0.277778 m/s |
| 2 km/h | 0.555556 m/s |

| 10 km/h | 2.777778 m/s |
| 20 km/h | 5.555556 m/s |
| 50 km/h | 13.888889 m/s |
| 100 km/h | 27.777778 m/s |
1 km/h = 0.277778 m/s
1 m/s = 3.6 km/h
Formula: value × 0.2777777778
Example: 15 km/h = 4.166667 m/s
Precision note: Use the exact relationship of 1 km/h = 0.2777777778 m/s. Keep more precision for calculations and round more for general display.
One kilometer per hour is exactly 0.2777777778 meters per second.
Because one kilometer is 1000 meters and one hour is 3600 seconds, so km/h to m/s uses the factor 1000/3600.
Meters per second is better for physics, engineering, acceleration, sensors, and calculations that use seconds.
