Show the working
  1. Width = 50
  2. Thickness = 6
  3. Length = 1000
  4. Number of pieces = 1
  5. volume_mm3 = 50 * 6 * 1000 = 300 000
  6. Volume of one piece = 300 000 / 1000 = 300
  7. Density used = 2810 = 2810
  8. Weight of one flat bar = 300 000 * 2810 / 1e9 = 0.843
  9. Total weight = 0.843 * 1 = 0.843
  10. Weight per metre of length = 300 000 / 1000 * 1000 * 2810 / 1e9 = 0.843

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 = width x thickness x length
    • Weight = volume x density, with density = 2810 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.

    Zinc-bearing aerospace alloy: the densest of the common wrought aluminums.

    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 7075 aluminum?

    2810 kg/m3, which is 2.810 g/cm3. Zinc-bearing aerospace alloy: the densest of the common wrought aluminums.

    How do you calculate the weight of a 7075 aluminum flat bar?

    Volume = width x thickness x length. Multiply the volume by the density of 7075 aluminum, 2810 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.
