Kilometers per hour to Meters per second Converter km/h → m/s

1 kilometer per hour (km/h) = 0.2777777778 meters per second (m/s). Type a value below, the conversion happens instantly, entirely on your device.

From

1 km/h = 0.2777777778 m/s

Precision

100 kilometers per hour = 27.777778 meters per second

100 × 0.277778 = 27.777778

1 km/h equals 0.277778 m/s, so multiplying by 0.277778 converts the value. The result describes the exact same quantity, only the measuring stick changes.

How to convert kilometers per hour to meters per second

meters per second = kilometers per hour × 0.2777777778, multiply the kilometer per hour value by 0.277778.

Example: 100 km/h = 27.7778 m/s.

To convert the other way: kilometers per hour = meters per second ÷ 0.2777777778 — or use the dedicated m/s to km/h converter .

Divide km/h by 3.6 for m/s: 100 km/h is 27.78 m/s. Physics problems want m/s, so this is the first step in most kinematics homework involving vehicle speeds.

About the units

What is a kilometer per hour?

Kilometers per hour (km/h) is the standard road-speed unit in most countries. 100 km/h equals 62.14 mph or 27.78 m/s.

What is a meter per second?

Meters per second (m/s) is the SI unit of speed. Physics calculations and wind speeds in scientific contexts use m/s; 1 m/s equals exactly 3.6 km/h.

Frequently asked questions

How many meters per second are in 1 kilometer per hour?

1 kilometer per hour (km/h) = 0.2777777778 meters per second (m/s).

What is the formula to convert kilometers per hour to meters per second?

meters per second = kilometers per hour × 0.2777777778, multiply the kilometer per hour value by 0.277778.

How do I convert km/h to m/s without a calculator?

Multiply by 0.278 for a close estimate. Exact factor: 1 km/h = 0.2777777778 m/s.

Is this km/h-to-m/s converter accurate and private?

Yes. It uses the exact internationally defined conversion factors and computes results locally in your browser, your input is never sent to a server, and the page keeps working offline.
