Velocity Calculator

Find velocity, distance or time from the other two quantities.

Worked example result
Velocity10.0000 m/s
Velocity36.0000 km/h
Distance100.0000 m
Time10.0000 s

Covering 100 m in 10 s is an average velocity of 10 m/s — exactly 36 km/h.

Average velocity is distance travelled divided by the time taken, assuming a steady speed or that you only need the overall average. This calculator can also rearrange the relation to find distance or time.

Pick a mode, then fill in the two known values — the value being solved for is ignored. Results give velocity in both metres per second and kilometres per hour.

The formula

v = d ÷ t; d = v × t; t = d ÷ v

Worked example

Covering 100 m in 10 s is an average velocity of 10 m/s — exactly 36 km/h.

Frequently asked questions

What is the difference between speed and velocity?

Speed is a magnitude only; velocity also has a direction. This calculator works with magnitudes along a straight path, so the numeric value is the same.

How do I convert m/s to km/h?

Multiply by 3.6. Conversely, divide km/h by 3.6 to get m/s. 10 m/s = 36 km/h.
