About the units

What is a km/h per second?

How many km/h the speed gains each second — intuitive for vehicles. 0 to 100 km/h in 5 s averages 20 km/h/s ≈ 5.56 m/s².

What is a metre per second²?

The SI unit of acceleration — the rate of change of velocity of one metre per second, each second. Earth's gravity is about 9.81 m/s².

Frequently asked questions

How many metres per second² are in 1 km/h per second?
