Yes, you can use it online for free without signup.

Steel Weight Calculator

Quickly calculate weight of round steel bars / rebar by diameter, length and quantity. Density used: 7850 kg/m³.

Bar Diameter

Length per Bar

Quantity Steel Density (kg/m³)

Formula used (round bar): weight(kg) = (π/4) × (d in m)² × length(m) × density(kg/m³). Shortcut: wt ≈ 0.006165 × d(mm)² × L(m).

Notes: Use mm for common rebar sizes. Inches/feet options convert automatically. Results are approximate—always verify with supplier.

Steel Weight Calculator – Calculate Steel Weight and Cost Instantly

Steel is one of the most important materials in construction. Whether you are working with TMT bars, steel rods, pipes, angles, channels, or sheets, knowing the exact weight of steel is essential for estimating cost, transportation, and structural planning. Our Steel Weight Calculator helps you calculate the weight of steel based on length, diameter, and shape. It is designed for contractors, engineers, students, fabricators, and anyone involved in construction or metalwork projects.

If your measurements include unwanted spaces or formatting issues, clean them using Remove Extra Spaces. To generate random values for testing, you may use Random Number Generator.

Why Use a Steel Weight Calculator?

Steel comes in many shapes and sizes, and each type has a different weight formula. Manual steel weight calculations can be confusing and error-prone, especially when dealing with different diameters, lengths, and densities. A Steel Weight Calculator helps you:

Get accurate steel weight quickly and effortlessly.
Estimate project cost by calculating total steel weight.
Plan transportation based on total load.
Reduce mistakes during manual calculations.
Save time during construction and planning.

For conversions like mm to inches or kg to pounds, use Unit Converter.

Standard Formula for Steel Weight

Steel has a standard density of 7850 kg/m³. The most commonly used formula for round steel bars (TMT bars) is:

Weight (kg) = (D² × L) / 162

D = Diameter in millimeters
L = Length in meters

This formula helps calculate weight for all TMT sizes: 6mm, 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, and more.

Steel Sections Supported by the Calculator

Our Steel Weight Calculator supports a wide range of steel shapes used in construction, fabrication, and industrial work:

TMT Bars (6mm–32mm)
Round Bars
Square Bars
Rectangular Bars
Steel Pipes (Round & Square)
Steel Sheets
MS Plates
Angles (L-Shaped)
Channels (C-Shaped)
I-Beams & H-Beams

For calculating concrete or mortar requirements for construction projects, try Concrete Calculator or Bricks Calculator.

How Steel Weight is Calculated (Shape-wise)

1. Round Bar / TMT Bar

Weight (kg/m) = (D × D) / 162

2. Square Bar

Weight = (Side × Side × Length × Density)

3. Steel Plate / Sheet

Weight = Length × Width × Thickness × Density

4. Steel Pipe (Round)

Weight = (Outer dia – Inner dia) × Thickness × Length × Density

5. Angle (L-Section)

Weight depends on the legs, thickness, and length.

Our calculator applies the correct formula automatically based on the steel type you select.
