To convert a measurement in kilometers per hour to a measurement in meters per second, multiply the speed by the following conversion ratio: 0.277778 meters per second/kilometer per hour.

Since one kilometer per hour is equal to 0.277778 meters per second, you can use this simple formula to convert:

meters per second = kilometers per hour × 0.277778

The speed in meters per second is equal to the speed in kilometers per hour multiplied by 0.277778.

For example, here's how to convert 5 kilometers per hour to meters per second using the formula above.

meters per second = (5 km/h × 0.277778) = 1.388889 m/s

Kilometers per hour and meters per second are both units used to measure speed.Calculate speed in kilometers per hour or meters per second using our speed calculator or keep reading to learn more about each unit of measure.

What Are Kilometers per Hour?

Kilometers per hour are a measurement of speed expressing the distance traveled in kilometers in one hour.

The kilometer per hour, or kilometre per hour, is an SI unit of speed in the metric system. Kilometers per hour can be abbreviated as km/h, and are also sometimes abbreviated as kph. For example, 1 kilometer per hour can be written as 1 km/h or 1 kph.

In the expressions of units, the slash, or solidus (/), is used to express a change in one or more units relative to a change in one or more other units.^[1] For example, km/h is expressing a change in length or distance relative to a change in time.

Kilometers per hour can be expressed using the formula:
v_km/h = d_km / t_hr

The velocity in kilometers per hour is equal to the distance in kilometers divided by time in hours.

What Are Meters per Second?

Meters per second are a measurement of speed expressing the distance traveled in meters in one second.

The meter per second, or metre per second, is the SI derived unit for speed in the metric system. Meters per second can be abbreviated as m/s, and are also sometimes abbreviated as m/sec. For example, 1 meter per second can be written as 1 m/s or 1 m/sec.

Meters per second can be expressed using the formula:
v_m/s = d_m / t_sec

The velocity in meters per second is equal to the distance in meters divided by time in seconds.
