Approximately how many metres per second do you travel when driving at 30 km/h?

30 km/h correspond to approximately 8 metres per second.

To respect and really understand the tremendous speeds at which you often travel when driving a car, it is good to know how many metres per second (*m/s*) different speeds correspond to.

**10 km/h**˜ 3 m/s**20 km/h**˜ 6 m/s**30 km/h**˜ 8 m/s**40 km/h**˜ 11 m/s**50 km/h**˜ 14 m/s**60 km/h**˜ 17 m/s**70 km/h**˜ 19 m/s**80 km/h**˜ 22 m/s**90 km/h**˜ 25 m/s**100 km/h**˜ 28 m/s**110 km/h**˜ 31 m/s**120 km/h**˜ 33 m/s

Divide the speed by 3.6 to convert kilometres per hour to metres per second. But if you just remember that 10 km/h equals about 3 m/s, the other speeds are easy to estimate.
