titanium hex bar weight calculator

Enter the dimensions of a titanium hex bar and this works out its volume and weight. Commercially pure titanium, grades 1 to 4.

Total weight
2.441 11kg
≈ Rounded titanium hex bar weight
Weight of one hex bar
2.441 11
Volume of one piece
541.266
Weight per metre of length
2.441 11 kg/m
Density used
4510 kg/m3
Show the working
  1. Across flats = 25
  2. Length = 1000
  3. Number of pieces = 1
  4. volume_mm3 = sqrt(3)/2 * 25^2 * 1000 = 541 266
  5. Volume of one piece = 541 266 / 1000 = 541.266
  6. Density used = 4510 = 4510
  7. Weight of one hex bar = 541 266 * 4510 / 1e9 = 2.441 11
  8. Total weight = 2.441 11 * 1 = 2.441 11
  9. Weight per metre of length = 541 266 / 1000 * 1000 * 4510 / 1e9 = 2.441 11

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 = (sqrt(3) / 2) x across-flats^2 x length
    • 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 hex bar?

    Volume = (sqrt(3) / 2) x across-flats^2 x length. 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.
