Question

express Km/h2 in m/s2

Answer 1

1 km = 1000m and 1 hour = 3600 sec 1km/h2 =1000/3600×3600
=0.00007716m/sec2

Answer 2

Hello,

If we need to convert km/h² to m/s² and vice versa, we need to know the relation between them.

So,..
1 km/h2 = 7.716049382716E-5 m/s2

And

1 m/s2 = 12960 km/h2


Hope it will help you.
