How Do You Convert km/h to m/s?

Answer – To convert km/h to m/s, multiply the given km/h value by the conversion factor $\frac{1000}{3600}$ or its simplified form $\frac{5}{18}$ . The solution is the equivalent value in m/s.

Explanation:

Begin by converting 1 km to m:

$1 k m = 1000 m$

Then, convert 1 h to s:

$1 h = 3600 s$

So $1 k m / h = \frac{1000}{3600} m / s = \frac{5}{18} m / s$

Use either of the above conversion factors – $\frac{1000}{3600}$ or $\frac{5}{18}$ – to express any km/h value in m/s.

For example:

$30 k m / h = 30 \times \frac{5}{18} m / s = 8.33 m / s$

Using $\frac{1000}{3600}$ instead of $\frac{5}{18}$ in the above expression also gives the same answer.
