Frequently Asked Questions
The weight is calculated using the formula: Weight = (π × d²/4) × L × ρ, where d is the diameter in meters, L is the length in meters, and ρ is the density of steel (typically 7850 kg/m³). For multiple bars, multiply by the number of bars.
The standard density of steel is 7850 kg/m³. You can adjust this value in the calculator if needed.
Diameter is in millimeters, length in meters, and density in kg/m³. The results are in kilograms for weight and meters for length.
Yes, simply enter the bar diameter in mm. Common sizes include 8, 10, 12, 16, 20, 25, 32 mm, etc.
