Steel Weight Per Foot Calculator

The Steel Weight Per Foot Calculator is a practical online tool designed to help engineers, fabricators, construction professionals, and metalworkers quickly determine the weight of steel bars, rods, or pipes based on their diameter and density.

In industries where precision matters, understanding the exact weight of steel per unit length is crucial for cost estimation, material planning, load calculations, and transportation logistics. This tool removes the need for manual formulas or guesswork — giving you instant, accurate results every time.

Whether you’re working with mild steel, carbon steel, stainless steel, or alloy steel, this calculator can help you determine the weight per foot in seconds, saving both time and effort.

⚙️ How the Steel Weight Calculator Works

This calculator operates on a simple physics-based formula that uses the entered diameter and density to calculate:

• Cross-sectional area (in square inches)
• Weight per foot (in pounds per foot)

The key formula used behind the scenes is: Weight per Foot=(π×(r2)×Density)×12\text{Weight per Foot} = (\pi \times (r^2) \times \text{Density}) \times 12Weight per Foot=(π×(r2)×Density)×12

Where:

• rrr = radius (in inches)
• Density = material density (in lb/in³)
• 12 = conversion from inches to feet

By inputting your diameter (in inches) and the density (default 0.283 lb/in³ for steel), the calculator provides:

• Cross-sectional area (in²)
• Weight per foot (lb/ft)

This method ensures reliable and scientifically accurate results suitable for technical and practical applications alike.

🧮 How to Use the Steel Weight Per Foot Calculator

Using the calculator is simple and requires just a few steps:

1. Enter the Diameter (in inches):
   Type in the diameter of your steel bar, rod, or tube. Example: 1.25.
2. Enter Density (optional):
   By default, the density is set to 0.283 lb/in³, which corresponds to mild steel.
   You can modify this value if you’re working with other metals (for instance, stainless steel ≈ 0.290 lb/in³).
3. Click “Calculate”:
   The tool will instantly compute the cross-sectional area and weight per foot.
4. View Your Results:
   The calculator displays:
   • Cross Sectional Area (in²)
   • Weight per Foot (lb/ft)
5. Reset Anytime:
   Hit the Reset button to clear inputs and perform a new calculation.

📊 Example: Calculate the Weight of a Steel Rod

Let’s say you have a steel rod with a diameter of 2 inches.

• Diameter = 2 inches
• Density = 0.283 lb/in³ (default)

Step 1: Calculate radius r=22=1 inchr = \frac{2}{2} = 1 \text{ inch}r=22​=1 inch

Step 2: Calculate cross-sectional area A=π×(1)2=3.142 in²A = \pi \times (1)^2 = 3.142 \text{ in²}A=π×(1)2=3.142 in²

Step 3: Weight per inch Winch=3.142×0.283=0.889lb/inW_{\text{inch}} = 3.142 \times 0.283 = 0.889 lb/inWinch​=3.142×0.283=0.889lb/in

Step 4: Weight per foot Wfoot=0.889×12=10.67 lb/ftW_{\text{foot}} = 0.889 \times 12 = 10.67 \text{ lb/ft}Wfoot​=0.889×12=10.67 lb/ft

✅ Result: A 2-inch diameter steel bar weighs approximately 10.67 lb per foot.
