How heavy is a metal sheet, and what might its metal be worth? Enter its size and material to estimate its weight and raw-material cost. This is a starting estimate, not a supplier’s final price.
The calculator follows the same simple chain every time.
Enter millimetres and the number of pieces.
Density turns the shape’s volume into weight.
Waste allowance raises the amount to buy.
Metal weight × price per kilogram = estimated value.
The calculator uses a material’s density: how much a set amount of space filled with it weighs. It combines density with your measurements to estimate kilograms. A price per kilogram then turns that weight into an estimated value.
One metre is 1,000 millimetres. Mixing those units would give a very wrong answer.
A copper sheet 1,000 mm long, 100 mm wide and 2 mm thick weighs about 1.792 kg using this tool’s density. At an example price of $10 per kg, its raw value is $17.92. These are teaching numbers, not a current copper quote.
Enter the finished dimensions above. Waste is applied to mass after geometry; purity is applied only to payable metal and value.
The tool finds the space inside the shape, called volume. It then uses the metal’s density to estimate weight. It does not subtract holes or allow for bends and cuts.
The waste setting adds extra material you may need to buy. Purity tells the tool how much of the weight is the chosen metal. Purity changes the metal value, not the object’s weight.
The estimate covers the metal itself. It does not include the cost of making the part, special alloys, small-order fees, tax, delivery or the seller’s profit.
The calculator uses the latest stored reference for each metal. Check the source and date on the copper, aluminium or nickel price pages, and read the industrial metals price guide to see why a benchmark is not a delivered price.
Volume is the space your finished pieces take up. Purchase mass is the estimated weight to buy, including the waste allowance. A 10% allowance adds 10% to the calculated weight; it is not a full cutting plan.
Purity describes how much of the weight counts as the chosen metal. For example, 80% of 10 kg is 8 kg. The tool changes the metal value, not the physical weight. An alloy’s true density can differ from the pure metal’s density.
Drilled holes, bends and size tolerances are not modelled. The result does not add labour, cutting, shipping, taxes or a seller’s profit. Check a supplier’s quote before using it as a project budget.
