How to convert kilometers per hour to meters per second
To convert a measurement in kilometers per hour to meters per second, multiply the value by 0.277777777778. The conversion factor comes from the relationship between both units and the meter per second.
For example, to convert 5 km/h to meters per second: 5 × 0.277777777778 = 1.388889 m/s.
What is a kilometer per hour?
The kilometer per hour is a metric unit of speed equal to one kilometer traveled in one hour, or exactly 1/3.6 meters per second. Km/h became the standard for road speed limits in most of the world as motor vehicles spread in the 20th century, pairing naturally with the metric system's kilometer.
Common uses of kilometers per hour include: Road speed limits in most countries; Vehicle speedometers worldwide; Weather reports for wind speed; Cycling and running pace tracking.
What is a meter per second?
The meter per second is the SI unit of speed, equal to the distance in meters traveled in one second. As the coherent SI unit of speed, m/s follows directly from the base units of length (meter) and time (second) and is the standard in physics and engineering worldwide.
Common uses of meters per second include: Physics and engineering calculations; Wind speed in scientific reporting; Athletic sprint and swim speeds; Fluid flow and machinery velocities.

Frequently asked questions
How many meters per second are in one kilometer per hour?
One kilometer per hour (km/h) equals 0.277777777778 meters per second (m/s). Multiply any value in kilometers per hour by 0.277777777778 to convert to meters per second.
How do I convert kilometers per hour to meters per second?
Multiply the value in kilometers per hour by 0.277777777778. For example, 5 km/h × 0.277777777778 = 1.388889 m/s.
How do I convert meters per second to kilometers per hour?
Multiply the value in meters per second by 3.6, or divide by 0.277777777778. Use the swap button on the converter above to reverse the direction.
Is the kilometer per hour to meter per second conversion exact?
Conversions between m/s, km/h, mph, knots and ft/s are exact by definition. Mach uses the speed of sound at sea level and 15°C (340.29 m/s), which varies with temperature and altitude.
What is the formula for kilometers per hour to meters per second?
The formula is: m/s = km/h × 0.277777777778. This comes from the definition of both units relative to the meter per second.
