Reinforced Steel Rod Weight Calculator

This calculator calculates the weight of reinforced steel rods based on their diameter and length.

Input Parameters

Calculation Results

Weight Calculation

Weight (kg) = (π × D² × L) / 4 × ρ

Where:
π = Pi (approximately 3.14159)
D = Diameter of the rod (mm)
L = Length of the rod (m)
ρ = Density of steel (7850 kg/m³ for mild steel)

Weight: 0.00 kg

Reinforced Steel Rod Weight Calculator Usage Guide

Learn how to use the calculator and understand the calculation principles.

How to Use the Calculator

  1. Enter the diameter of the steel rod in millimeters (mm). This is the width of the rod.
  2. Enter the length of the steel rod in meters (m). This is the height of the rod.
  3. Click the "Calculate" button to compute the weight.
  4. The result will be displayed in kilograms (kg).

Understanding the Calculation

The calculator uses the formula:

Weight (kg) = (π × D² × L) / 4 × ρ

Where:

  • π (pi): A mathematical constant approximately equal to 3.14159
  • D: Diameter of the rod in millimeters (mm)
  • L: Length of the rod in meters (m)
  • ρ (rho): Density of steel, which is approximately 7850 kg/m³ for mild steel

Example

If you have a steel rod with a diameter of 12 mm and a length of 3 meters:

Weight = (3.14159 × 12² × 3) / 4 × 7850 = 8.54 kg

Applications

This calculator is useful for civil engineers, construction professionals, and anyone working with reinforced steel in construction projects. It helps estimate material requirements and costs.
