Pound Mass to Pound Force Formula
The following equation is used to calculate the Pound-Mass to Pound-Force.
lbf = m * g
- Where lbf is the pounds of force (lb-f)
- m is the mass of the object (lbs)
- g is the acceleration due to gravity (32.174049 ft/s^2)
To calculate the pound-force from pound mass, multiply the mass in pounds by the acceleration in feet per second squared.
What is the difference between Pound Mass and Pound Force?
A pound-mass is defined as a mass equal to .45359237 kilograms.
A pound-force is the amount of force exerted on one pound mass due to gravity.
How to Calculate Pound Force from Pound Mass?
The following example outlines the steps and information needed to calculate pound force from pound mass.
First, determine the total mass in pounds. Using an accurate scale, the mass of this object is found to be 15 lbs.
Next, the final and last step is to use the formula above to calculate the pound-force due to gravity.
lbf = lb * g
lbf = 15 * 32.174049
lbf = 482.61 lb-f
