Weight of one square tube: 2.543 64
Volume of one piece: 564
Weight per metre of length: 2.543 64 kg/m
Density used: 4510 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 = 4510 = 4510
Weight of one square tube = 564 000 * 4510 / 1e9 = 2.543 64
Total weight = 2.543 64 * 1 = 2.543 64
Weight per metre of length = 564 000 / 1000 * 1000 * 4510 / 1e9 = 2.543 64

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 = 4510 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 titanium, grades 1 to 4.

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 titanium?

4510 kg/m3, which is 4.510 g/cm3. Commercially pure titanium, grades 1 to 4.

How do you calculate the weight of a titanium square tube?

Volume = (side^2 - inner side^2) x length, ignoring the corner radii. Multiply the volume by the density of titanium, 4510 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.
