Weight Per Foot Formula
Weight per length equals total mass divided by length. The calculator also solves total mass or length, and estimates linear mass from four ideal cross-section shapes and a selected density. Here โweightโ is expressed in mass units (lb or kg), not force units.
Variables:
- WPF is the Weight Per Foot (lbs/ft)
- W is the total weight (lbs)
- L is the total length (ft)
To calculate lb/ft, divide mass in pounds by length in feet. Unit controls convert entered quantities; kg/m is also available. For shape estimates, linear mass = cross-sectional area ร density. Preset densities are illustrative; a custom density is interpreted in its selected unit.
How to Calculate Weight Per Foot?
The following steps outline how to calculate the Weight Per Foot.
- First, determine the total weight (lbs).
- Next, determine the total length (ft).
- Next, gather the formula from above = WPF = W / L.
- Finally, calculate the Weight Per Foot.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
total weight (lbs) = 30
total length (ft) = 10
WPF = W / L = 30 lb / 10 ft = 3 lb/ft
