## Pound Mass Formula

The following formula is used to calculate the Pound Mass.

**PM = PF / a**

- Where PM is the Pound Mass (lbs)
- PF is the pound force (lbf)
- a is the acceleration due to gravity (ft/s^2)

## How to Calculate Pound Mass?

The following example problems outline how to calculate Pound Mass.

Example Problem #1:

- First, determine the pound force (lbf).
- The pound force (lbf) is given as: 500.

- Next, determine the acceleration due to gravity (ft/s^2).
- The acceleration due to gravity (ft/s^2) is provided as: 32.174049.

- Finally, calculate the Pound Mass using the equation above:

PM = PF / a

The values given above are inserted into the equation below and the solution is calculated:

PM = 500 / 32.174049 = 15.540 (lbs)

Example Problem #2:** **

For this problem, the variables needed are provided below:

pound force (lbf) = 600

acceleration due to gravity (ft/s^2) = 32.174049

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.
