Rebar Weight Calculator — Calculate Steel Reinforcement Weight

Rebar Weight Calculator

Calculate the weight of steel reinforcement bars (rebar) for construction projects. Determine total weight based on diameter, length, quantity, and steel density for accurate material estimation.

Step 1: Rebar Specifications

6 m
10

Standard Rebar Sizes

Common rebar diameters range from 6mm to 40mm. The weight per meter increases with diameter. Standard lengths are typically 6m or 12m, but custom lengths can be specified.

Step 2: Calculation Parameters

7850 kg/m³

Steel Density Information

Standard steel density is 7850 kg/m³ (0.2836 lbs/in³). Mild steel reinforcement typically ranges from 7850-8050 kg/m³ depending on alloy composition and manufacturing process.

Weight Calculation Breakdown

Rebar Weight Formula

Weight = (π × (Diameter/1000)² / 4) × Length × Quantity × Density

To calculate rebar weight: Calculate cross-sectional area from diameter, multiply by length, quantity, and steel density. Convert diameter from mm to meters for consistency.
