410 stainless steel square bar weight calculator

Enter the dimensions of a 410 stainless steel square bar and this works out its volume and weight. Martensitic stainless, hardenable and slightly lighter than the austenitic grades.

Density used
7740 kg/m3
Show the working
  1. Side = 25
  2. Length = 1000
  3. Number of pieces = 1
  4. volume_mm3 = 25^2 * 1000 = 625 000
  5. Volume of one piece = 625 000 / 1000 = 625
  6. Density used = 7740 = 7740
  7. Weight of one square bar = 625 000 * 7740 / 1e9 = 4.8375
  8. Total weight = 4.8375 * 1 = 4.8375
  9. Weight per metre of length = 625 000 / 1000 * 1000 * 7740 / 1e9 = 4.8375

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 x length
    • Weight = volume x density, with density = 7740 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.

    Martensitic stainless, hardenable and slightly lighter than the austenitic grades.

    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 410 stainless steel?

    7740 kg/m3, which is 7.740 g/cm3. Martensitic stainless, hardenable and slightly lighter than the austenitic grades.

    How do you calculate the weight of a 410 stainless steel square bar?

    Volume = side^2 x length. Multiply the volume by the density of 410 stainless steel, 7740 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.
