Conversion Formulas
Feel free to convert kilometers per hour to meters per second (km/h to m/s) and meters per second to kilometers per hour (m/s to km/h) using our conversion chart, and conversion calculator, and learn the relationship between these two units.
Conversion of kilometers per hour to meters per second (km/h to m/s) and meters per second to kilometers per hour (m/s to km/h) is an easy one since both units are used for measuring speed.
Meters and kilometers are used to measure length, while seconds and hours are used to measure time.
Their relationships are as follows:
1 kilometer (km) = 1000 m → 1 meter = 1/1000 km
1 hour (h) = 3600 seconds → 1 second = 1/3600 hour
Thus, if we want to convert km/h to m/s and m/s to km/h, we can write:
1 km/h = 1000 m / 3600 s = 0.27777 m/s
1 m/s = (1/1000) kilometers / (1/3600) hour = 3600 km / 1000 h = 3.6 km/h
These last two formulas allow us to easily convert m/s to km/h and km/h to m/s.
Kilometers per Hour to Meters Per Second (km/h to m/s) and Meters Per Second to Kilometers per Hour (m/s to km/h) Conversion Examples
How many km/h is 4 m/s?
In order to convert the speed given in meters per second to the speed in km/h, we can write:
v = 4 m/s = 4 * 3.6 km/h = 14.4 km/h
So, 4 m/s is equal to 14.4 km/h.
How many m/s is 16 km/h?
In order to convert the speed given in km/h to the speed given in meters per second, we can write
v = 16 km/h = 16 / 3.6 m/s = 4.444 m/s
So, 16 km/h is equal to 4.444 m/s.
100 km/h to m/s:
v = 100 / 3.6 = 27.77 m/s
100 m/s to km/h:
v = 100 * 3.6 m/s = 360 km/h
etc.
