Question

Dear expert,

How to convert m/sec to km/hr and km/hr to m/sec?

Answer 1

1 m/s = 3.6 km/h

or

1 km/h = (1/3.6) m/s = 5/18 m/s = 0.277 m/s

it comes out as follows

we know that 1 km = 1000 m

and 1 hr = 3600 secs

thus

1 km/hr = 1 km/1hr = 1000 m / 3600s

= (10/36) m/s = 5/18 m

so,

1 km/hr = (5/18) m/s

or

1m/s = (18/5) km/hr
