Weight per metre of length: 3.937 95 kg/m
Density used: 8890 kg/m3

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 = 8890 = 8890
Weight of one round tube = 442 965 * 8890 / 1e9 = 3.937 95
Total weight = 3.937 95 * 1 = 3.937 95
Weight per metre of length = 442 965 / 1000 * 1000 * 8890 / 1e9 = 3.937 95

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 = 8890 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.

Nickel-molybdenum-chromium alloy for aggressive chemical service.

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 Hastelloy C-276?

8890 kg/m3, which is 8.890 g/cm3. Nickel-molybdenum-chromium alloy for aggressive chemical service.

How do you calculate the weight of a Hastelloy C-276 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 Hastelloy C-276, 8890 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.
