Procedure for Steel Weight Calculation in Construction

Steel bars are typically calculated based on their unit weight, which is derived from their diameter and length. The most common formula used for calculating the weight of steel bars (in kilograms) is:

Weight of steel bar (kg) = D²/162×L

Where:

• D is the diameter of the steel bar in millimeters.
• L is the length of the bar in meters.
• The constant 162 is derived from the density of steel (7850 kg/m³).

This formula is applicable for estimating the weight of round steel bars (TMT, rebar) commonly used in construction.

Explanation of Terms:

• Diameter (D): The diameter of the steel bar is crucial because it determines its cross-sectional area.
• Length (L): This is the length of the bar, usually measured in meters.
• Constant 162: This value simplifies the calculation based on the properties of steel and unit conversions (from cubic meters to kilograms).

Example Calculation:

For a steel bar with a diameter of 12 mm and a length of 5 meters, the weight would be calculated as:

Weight of steel bar (kg) = D²/162×L = 144/162×5 = 4.44 kg
