Angular momentum is a fundamental concept in classical physics, but its concrete physical meaning can vary according to the context. The symbol for angular momentum is usually denoted as J and spelled as “momentum”.
Angular Momentum Units are metric units of angular velocity. One unit of angular momentum equals 1 kiloPascal-seconds (ksp-s). In American Engineering Measurement Units, one unit of angular momenta equals 6.8349584 dB-in2-s1/4 or approximately 850 femtometers per square second (mn/sq) or 1750 microradians per square second (μrad/sq).
