Steel Bar Weight Per Foot Calculator

Steel Bar Weight Per Foot Formula

The weight per foot (W/ft) of a steel bar is calculated using the formula:

\[ \text{W/ft} = \pi \times \left(\frac{D}{2 \times 12}\right)^2 \times d \]

Where:

• \( D \) is the diameter of the bar in inches
• \( d \) is the density of steel in pounds per cubic foot (default: 490 lbs/ft³)

Example Calculation

If the diameter of a steel bar is 1 inch, and the density of steel is 490 lbs/ft³, the weight per foot would be:

\[ \text{W/ft} = \pi \times \left(\frac{1}{2 \times 12}\right)^2 \times 490 \approx 1.067 lbs \]

Importance and Usage Scenarios

Calculating the weight per foot of a steel bar is essential in various construction and engineering projects to determine the load, transportation requirements, and material costs accurately. This calculator provides a quick and easy way to determine the weight of a steel bar based on its diameter and the density of the material.

Common FAQs

1. What is the default density of steel used in this calculator?

   • The default density is 490 lbs/ft³, which is commonly used for standard steel.

2. How can I change the density for other materials?

   • You can input a different density value in the calculator for different types of steel or other materials.

3. Why is the diameter divided by 12 in the formula?

   • The division by 12 converts the diameter from inches to feet for consistent units with the density in lbs/ft³.
