Inconel 718 square tube weight calculator
Enter the dimensions of a Inconel 718 square tube and this works out its volume and weight. Precipitation-hardened nickel superalloy.
- Weight of one square tube
- 4.619 16
- Volume of one piece
- 564
- Weight per metre of length
- 4.619 16 kg/m
- Density used
- 8190 kg/m3
Show the working
- Outside side = 50
- Wall thickness = 3
- Length = 1000
- Number of pieces = 1
- volume_mm3 = (50^2 - (50 - 2*3)^2) * 1000 = 564 000
- Volume of one piece = 564 000 / 1000 = 564
- Density used = 8190 = 8190
- Weight of one square tube = 564 000 * 8190 / 1e9 = 4.619 16
- Total weight = 4.619 16 * 1 = 4.619 16
- Weight per metre of length = 564 000 / 1000 * 1000 * 8190 / 1e9 = 4.619 16
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 = (side^2 - inner side^2) x length, ignoring the corner radii
- Weight = volume x density, with density = 8190 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.
Precipitation-hardened nickel superalloy.
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 Inconel 718?
8190 kg/m3, which is 8.190 g/cm3. Precipitation-hardened nickel superalloy.
How do you calculate the weight of a Inconel 718 square tube?
Volume = (side^2 - inner side^2) x length, ignoring the corner radii. Multiply the volume by the density of Inconel 718, 8190 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.
