Velocity

m/s to km/h conversion

Convert metre per second (m/s) to kilometre per hour (km/h). Velocity is distance per unit time — the line-sizing quantity that flags erosion, noise, and pressure drop.

1 m/s = 3.6 km/h

Formula

To convert metre per second to kilometre per hour, multiply the m/s value by 3.6. To go the other way, divide by 3.6 (or multiply by 0.2777778).

Used in practice

Line velocities are checked in m/s or ft/s against service-specific guidance bands.

High velocity means high friction loss and erosion risk; low velocity risks settling in slurry lines.

Worked example. A velocity of 2 m/s is 7.2 km/h.

Frequently asked questions

How do you convert metre per second to kilometre per hour?

Multiply the value in m/s by 3.6 to get km/h. For example, 10 m/s = 36 km/h.

What is 1 m/s in km/h?

1 m/s equals 3.6 km/h.
