Metal Weight Calculator

Metal Weight Calculator turns stock dimensions and alloy into weight and cost, for a single piece or a whole cut list - with the formula shown on screen.

Use this metal weight calculator for round bar, square bar, flat bar, sheet, round tube, square tube, rectangular tube, hex bar, and angle, in eleven common alloys, converting length x cross-sectional area x density into pounds and kilograms together.

WEIGHT
- Choose a profile: round bar, square bar, flat bar/plate, sheet, round tube, square tube, rectangular tube, hexagon bar, or angle
- Enter the profile's dimensions and pick an alloy - mild steel, 304 or 316 stainless, 6061 or 5052 aluminum, brass, bronze, copper, titanium grade 2, cast iron, lead, or zinc
- Enter length and quantity
- See weight per piece and total weight in pounds and kilograms
- Enter a price per pound or per kilogram to see total cost
- Keep a history of calculated results

CUT LIST
- Build a running list of cut lengths and quantities against your chosen material and profile
- See total weight, total pieces, and total length for the list
- See total cost when a price is set
- Run stock optimization: enter a stock bar length and kerf width to see how many stock lengths you need and the leftover drop
- Edit or delete any line item

STOCK
- Save named presets of profile, dimensions, alloy, and price
- Load a saved preset back into the Weight tab

BUILT FOR SHOP AND YARD WORK
- Fast entry with minimal taps
- Works offline
- No account required
- Your cut list and presets stay on your device

Rolled sections like channel and I-beam are intentionally not included - their fillets and taper mean a simple rectangle formula would quietly misstate the true weight, and this app does not ship a number it cannot back with a real dimension table.

This app is ad-supported. The calculators are available to use; watching a short ad unlocks saving results, calculation history, and saved stock presets.

If you need a metal weight calculator or steel weight calculator for bar, tube, sheet, or angle stock, plus a cut list with stock optimization, this app gives you the numbers with the formula shown.
