Metal is bought by weight and sold by the piece or the metre. Work out the weight of any bar, sheet, pipe or angle, and its price per piece, in seconds.
Weight = cross-section area x length x density. Steel weighs 7,850 kg per cubic metre, stainless about 8,000, aluminium 2,700 and copper 8,960. Dimensions can be in millimetres or inches; length is in metres.
Example: a 12 mm round steel bar 12 m long weighs about 0.888 kg per metre, so 10.65 kg a bar and 106.5 kg for 10 bars. A 1,250 x 2,500 mm steel sheet 2 mm thick weighs about 49.1 kg; at 1.20 per kg it costs about 58.88.
Pick the shape and enter its dimensions.
Up Stock tracks bars, sheets and pipes by the piece in every store, records credit sales to contractors, and shows which sizes are tying up your cash.
Mills roll to tolerances, and angles and tubes have rounded corners. Calculated weights are theoretical and usually within a few percent of the real ones.
Enter the price per kg and the calculator multiplies it by the weight of each piece and of the whole order.
Rebar is carbon steel, 7,850 kg per cubic metre. Use its nominal diameter.
Yes. Switch the unit to inches for the dimensions; length stays in metres.
