About Steel Weight Calculator
Steel Weight Calculator — Quickly estimate the weight of steel reinforcement bars (TMT bars), plates, and rods based on their diameter and total length.
How to use the Steel Weight Calculator
- Select the diameter of the steel bar (in mm) like 8mm, 10mm, 12mm, etc.
- Enter the total length of the bar (in meters or feet).
- Click Calculate to find the total theoretical weight in kilograms instantly.
FAQs
What is the formula for calculating steel weight?
The standard formula for calculating the weight of a circular steel rod per meter is (D² / 162), where D is the diameter of the bar in millimeters. The result is the weight in kg/m.
What is the density of mild steel?
The theoretical density of mild steel is approximately 7,850 kg per cubic meter (kg/m³). This constant is used in our calculator to provide accurate weight estimates for various steel profiles.
