Enter the angular momentum and the mass into the calculator to determine the Specific Angular Momentum. 

Specific Angular Momentum Formula

The following equation is used to calculate the Specific Angular Momentum.

h = L / m

  • Where h is the Specific Angular Momentum (m/s)
  • L is the angular momentum (kg*m/s)
  • m is the mass (kg)

What are the units for Specific Angular Momentum?

The most common units for Specific Angular Momentum are m/s.

How to Calculate Specific Angular Momentum?

Example Problem:

The following example problem outlines the steps and information needed to calculate the Specific Angular Momentum.

First, determine the angular momentum. In this example, the angular momentum is determined to be 120 (kg*m/s).

Next, determine the mass. For this problem, the mass is measured to be 6 (kg).

Finally, calculate the Specific Angular Momentum using the formula above: 

h = L / m

Inserting the values from above and solving the equation with the imputed values gives: 

h = 120/ 6 = 20 (m/s)
