nickel hex bar weight calculator
Enter the dimensions of a nickel hex bar and this works out its volume and weight. Commercially pure nickel, Alloy 200.
- Weight of one hex bar
- 4.817 27
- Volume of one piece
- 541.266
- Weight per metre of length
- 4.817 27 kg/m
- Density used
- 8900 kg/m3
Show the working
- Across flats = 25
- Length = 1000
- Number of pieces = 1
- volume_mm3 = sqrt(3)/2 * 25^2 * 1000 = 541 266
- Volume of one piece = 541 266 / 1000 = 541.266
- Density used = 8900 = 8900
- Weight of one hex bar = 541 266 * 8900 / 1e9 = 4.817 27
- Total weight = 4.817 27 * 1 = 4.817 27
- Weight per metre of length = 541 266 / 1000 * 1000 * 8900 / 1e9 = 4.817 27
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 = 8900 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 nickel, Alloy 200.
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 nickel?
8900 kg/m3, which is 8.900 g/cm3. Commercially pure nickel, Alloy 200.
How do you calculate the weight of a nickel hex bar?
Volume = (sqrt(3) / 2) x across-flats^2 x length. Multiply the volume by the density of nickel, 8900 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.
