titanium round bar weight calculator

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

Total weight
2.213 84kg
≈ Rounded titanium round bar weight
Weight of one round bar
2.213 84
Volume of one piece
490.874
Weight per metre of length
2.213 84 kg/m
Density used
4510 kg/m3
Show the working
  1. Diameter = 25
  2. Length = 1000
  3. Number of pieces = 1
  4. volume_mm3 = pi * (25/2)^2 * 1000 = 490 874
  5. Volume of one piece = 490 874 / 1000 = 490.874
  6. Density used = 4510 = 4510
  7. Weight of one round bar = 490 874 * 4510 / 1e9 = 2.213 84
  8. Total weight = 2.213 84 * 1 = 2.213 84
  9. Weight per metre of length = 490 874 / 1000 * 1000 * 4510 / 1e9 = 2.213 84

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 x (diameter / 2)^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 round bar?

    Volume = pi x (diameter / 2)^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.
