cast aluminum sheet weight calculator

Enter the dimensions of a cast aluminum sheet and this works out its volume and weight. Nominal for A356 and similar silicon casting alloys.

Total weight
15.96kg
= Exact cast aluminum sheet weight
Weight of one sheet
15.96
Volume of one piece
6000
Density used
2660 kg/m3
Show the working
  1. Length = 2000
  2. Width = 1000
  3. Thickness = 3
  4. Number of pieces = 1
  5. volume_mm3 = 2000 * 1000 * 3 = 6 000 000
  6. Volume of one piece = 6 000 000 / 1000 = 6000
  7. Density used = 2660 = 2660
  8. Weight of one sheet = 6 000 000 * 2660 / 1e9 = 15.96
  9. Total weight = 15.96 * 1 = 15.96

Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

    The formula

    • Volume = length x width x thickness
    • Weight = volume x density, with density = 2660 kg/m3
    • One cubic millimetre of a material at 1000 kg/m3 weighs exactly one milligram, so the millimetre-to-kilogram step is a shift of the decimal point rather than a rounded factor.

    Nominal for A356 and similar silicon casting alloys.

    Dimensions are nominal. Mill tolerances on thickness, and the corner radii on formed sections, both move the real weight by a percent or two.

    Every field takes inches or feet as readily as millimetres: change the unit next to it and the conversion is done exactly before the arithmetic starts.

    Frequently asked

    What is the density of cast aluminum?

    2660 kg/m3, which is 2.660 g/cm3. Nominal for A356 and similar silicon casting alloys.

    How do you calculate the weight of a cast aluminum sheet?

    Volume = length x width x thickness. Multiply the volume by the density of cast aluminum, 2660 kg/m3, taking care that both are in the same unit system.

    Can I enter dimensions in inches?

    Yes. Each dimension field has its own unit selector, and inch, foot, millimetre, centimetre and metre entries are all converted exactly before anything is multiplied.

    Where the numbers come from

    • Densities are nominal room-temperature values for the grade named, drawn from the usual mill and handbook figures.
