Question

How to convert km per second to km per hour?

Answer 1

One second is equal to $\frac{1}{3600}$ hours

The unit is km/s, which means $\frac{1km}{1s}$. So to convert it into km/h, simply put 1 second as $\frac{1}{3600}$ hours

Therefore, $\frac{1km}{ \frac{1}{3600}hours}$ = $\frac{1km*3600}{1hour}$ = 3600km/h

Answer 2

To convert Km/sec into Km/hr, do these following steps:

1. Write the values with units. For instance 0.01 Km/sec.
2. We know that 1 hr = 3600 sec
               or 3600 sec = 1 hr
                         1 sec = 1/3600 hr
             so, 1/(1 sec) = 3600 hr
3. Now, we can see that to convert 0.01 Km/sec into Km/hr,
                  (0.01×3600) Km/hr 
                   36 Km/hr
