Metal Weight and Price Calculator

Formula

• Weight = volume × density
• Volume from section geometry (mm³)
• Weight (kg) = volume × density(g/cm³) / 10⁶

About this calculator

Part of our Manufacturing Calculators collection. Welding, stamping, punch and die tooling, 3D printing, material weight, and production automation.

How it works

Volume comes from the selected section shape and entered dimensions. Weight equals volume times density. Total price applies your per-kilogram rate, quantity, and margin. Use this for quoting raw stock before machining or fabrication.

Enter your values in the inputs above and click CALCULATE. Results appear on the right without a page reload. No login and no server upload.

Worked example

Rectangular bar 50 × 25 mm, length 1000 mm, steel density 7.85 g/cm³.

1. Volume = 50 × 25 × 1000 = 1,250,000 mm³
2. Weight = 1,250,000 × 7.85 / 10⁶ = 9.81 kg

Result: Unit weight 9.81 kg; at ₹85/kg → ₹834 per piece.

When to use

• Quoting raw material weight for bids
• Checking shipping weight for stock lengths
• Estimating material cost with margin

Limitations

• Shape dropdown labels now match formula indices — verify dimensions for your section
• No kerf or scrap allowance
• Density is user-entered; alloys vary

FAQ

What was fixed in the shape selector?

Previous labels did not match the volume formulas (e.g. round bar was mislabeled). Dropdown options now align with each formula case.

Which dimension is which?

Each shape label describes dims A, B, C, D. Round bar uses A as diameter; tube uses A = OD, B = wall thickness.

How do units work?

Pick input units once; all dimensions and length convert to mm internally before volume is calculated.
