Angular momentum is a physical quantity that relates to something’s moment of inertia and rotational speed. Angular momentum can be quantified by the position vector r of an object with respect to some origin, multiplied formula_1 (angular velocity), or alternatively as the moment of inertia times its angular acceleration.
The SI unit for measuring angular momentum is Newton meter squared per kilogram, which is typically shortened to just newton-meter-squared.
This cancels out since both are meters so it then becomes kilograms times newtons over seconds squared.
