The Brass Rod Weight Calculator is a free online tool designed to help engineers, fabricators, contractors, and metal suppliers quickly calculate the weight of brass rods based on diameter, length, and density.
It uses standard engineering formulas to ensure accurate and reliable results. This tool is ideal for estimating material requirements, transport loads, and cost calculations in manufacturing, plumbing, and architectural projects.
By using this calculator, you save time, avoid manual errors, and get precise weight, volume, and cross-sectional area instantly, all from your browser.
How to Use the Brass Rod Weight Calculator
- Enter the Diameter (mm): Type the outer diameter of your brass rod in millimetres.
- Enter the Length (m): Provide the total length of the rod in meters.
- Enter the Density (kg/m³): The default brass density is 8500 kg/m³, which you can change if needed.
- Click “Calculate”: The tool instantly shows the estimated weight, cross-sectional area, and volume of the rod.
- Optional Tools: Use “Export CSV” to download the results or “Copy Summary” for easy sharing.
Formula Used
The calculator uses the cylindrical volume formula combined with material density to determine total weight.
Weight (kg) = Volume × Density
where,
Volume = π × r² × L
Substituting r = d / 2,
Weight (kg) = π × (d / 2)² × L × Density
Variables:
- d = Diameter of the rod (m)
- L = Length of the rod (m)
- Density = Material density (kg/m³)
Example Calculation
Suppose you have a brass rod with:
- Diameter = 50 mm (0.05 m)
- Length = 2 m
- Density = 8500 kg/m³
Then,
Weight = π × (0.05 / 2)² × 2 × 8500
Weight = 3.1416 × (0.025)² × 2 × 8500
Weight ≈ 33.4 kg
Result: The brass rod weighs approximately 33.4 kilograms.
