Question

How do you convert $km/hr$ to $m/s$?

Answer 1

Step 1: Given Data

The given unit is $km/hr$.

We are required to convert it to $m/s$.

Step 2: Explanation

SI unit of distance is a meter and of time is second according to the International System of Units.

$1km=1000m$

$1hr=60min$

$1min=60sec$

Therefore $1hr=60\times 60sec=3600sec$

Step 3: Calculation

So $1km/hr=\frac{1000}{3600}m/s$

$$\begin{gathered} =\frac{5}{18}m/s \\ =0.28m/s \end{gathered}$$

So, to convert km/h to m/s we multiply the given number by $\frac{5}{18}m/s$ or $0.28m/s$.
