Enter the diameter of the steel bar into the calculator to determine the weight per foot of steel bar.

## Steel Bar Weight Per Foot Formula

the following formula is used to calculate the weight per foot of a steel bar.

W/ft = pi*(D/2/12)^2*d

• Where W/ft is the weight per foot
• D is the diameter of the bar (in)
• d is the density of steel
• 490 lbs/ft^3

## What is a steel bar weight per foot?

The weight of a steel bar per foot is determined by the diameter of the bar and the density of the material. In this case, the material is steel, so the densities should be known.

## How to calculate steel bar weight per foot?

Example Problem:

The following example problem outlines how to calculate the weight of a steel bar per length of one foot.

First, determine the diameter of the bar. In this example, the diameter of the steel bar is measured to be 5 inches.

Next, determine the density of the steel. Normal steel has a density of 490 lbs/ft^3, so that’s what we will use for this example. Keep in mind that the density of the steel can vary depending on the makeup up the steel. A quick google search should yield the density of the steel you are using.

Finally, calculate the steel bar weight per foot using the formula above:

W/ft = pi*(D/2/12)^2*d

W/ft = 3.14159*(5/2/12)^2*490

W/ft = 66.8133 lbs/ft
