Newton. Unit of force represents (kg x m) / s^-2.
(note that it is minus square of second)

N is a Newton and is the unit for force. A Newton is that force which produces an acceleration of 1 metre per second per second on a mass of 1 kilogram.
Velocity is usually expressed as metres per second (kilometers per hour can be converted) and acceleration is change in velocity. So it is expressed as meters per second squared or m/s^2

The newton (symbol: N) is the unit of force.
or
The amount of force required to accelerate a body with a mass of one kilogram at a rate of one meter per second squared.
N = (kg x m) / s^2

In momentum
Impulse = F.t
Momentum = mv
impulse = momentum change
F.t = M.( Vf - Vi)
so
N.hr = kg.km/hr
then N=kg. km/ (hr.hr)
