2024 aluminum round tube weight calculator

Enter the dimensions of a 2024 aluminum round tube and this works out its volume and weight. Copper-bearing aircraft alloy.

≈ Rounded 2024 aluminum round tube weight
Weight of one round tube
1.231 44
Volume of one piece

Show the working
  1. Outside diameter = 50
  2. Wall thickness = 3
  3. Length = 1000
  4. Number of pieces = 1
  5. volume_mm3 = pi/4 * (50^2 - (50 - 2*3)^2) * 1000 = 442 965
  6. Volume of one piece = 442 965 / 1000 = 442.965
  7. Density used = 2780 = 2780
  8. Weight of one round tube = 442 965 * 2780 / 1e9 = 1.231 44
  9. Total weight = 1.231 44 * 1 = 1.231 44
  10. Weight per metre of length = 442 965 / 1000 * 1000 * 2780 / 1e9 = 1.231 44

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 = (pi / 4) x (OD^2 - ID^2) x length, where ID = OD - 2 x wall
    • Weight = volume x density, with density = 2780 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.

    Copper-bearing aircraft alloy.

    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 2024 aluminum?

    2780 kg/m3, which is 2.780 g/cm3. Copper-bearing aircraft alloy.

    How do you calculate the weight of a 2024 aluminum round tube?

    Volume = (pi / 4) x (OD^2 - ID^2) x length, where ID = OD - 2 x wall. Multiply the volume by the density of 2024 aluminum, 2780 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.
