ABS pipe weight calculator
Enter the dimensions of a ABS pipe and this works out its volume and weight. Acrylonitrile butadiene styrene, unfilled.
- Weight of one pipe
- 0.460 683
- Volume of one piece
- 442.965
- Weight per metre of length
- 0.460 683 kg/m
- Density used
- 1040 kg/m3
Show the working
- Outside diameter = 50
- Wall thickness = 3
- Length = 1000
- Number of pieces = 1
- volume_mm3 = pi/4 * (50^2 - (50 - 2*3)^2) * 1000 = 442 965
- Volume of one piece = 442 965 / 1000 = 442.965
- Density used = 1040 = 1040
- Weight of one pipe = 442 965 * 1040 / 1e9 = 0.460 683
- Total weight = 0.460 683 * 1 = 0.460 683
- Weight per metre of length = 442 965 / 1000 * 1000 * 1040 / 1e9 = 0.460 683
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 = 1040 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.

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 ABS?
1040 kg/m3, which is 1.040 g/cm3. Acrylonitrile butadiene styrene, unfilled.
How do you calculate the weight of a ABS pipe?
Volume = (pi / 4) x (OD^2 - ID^2) x length, where ID = OD - 2 x wall. Multiply the volume by the density of ABS, 1040 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.
