1100 aluminum flat bar weight calculator

Enter the dimensions of a 1100 aluminum flat bar and this works out its volume and weight. Commercially pure aluminum, 99.0% minimum.

Total weight
0.813kg
= Exact 1100 aluminum flat bar weight
Weight of one flat bar

Weight per metre of length
0.813 kg/m
Density used
2710 kg/m3
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 = 2710 = 2710
  8. Weight of one flat bar = 300 000 * 2710 / 1e9 = 0.813
  9. Total weight = 0.813 * 1 = 0.813
  10. Weight per metre of length = 300 000 / 1000 * 1000 * 2710 / 1e9 = 0.813

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 = 2710 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.

    Commercially pure aluminum, 99.0% minimum.

    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 1100 aluminum?

    2710 kg/m3, which is 2.710 g/cm3. Commercially pure aluminum, 99.0% minimum.

    How do you calculate the weight of a 1100 aluminum flat bar?

    Volume = width x thickness x length. Multiply the volume by the density of 1100 aluminum, 2710 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.
