Theoretical Metal Weight Calculation Formula: 30 Types of Metals

If you’re working in the metalworking industry, even you’re engineers, you will try to find one calculator to help you calculate the weight of various metals and steels including ms plate, gi sheet, structural steel, ms angle, mild steel, steel bar, square tube, angle, aluminum etc.

Theoretical Metal Weight Calculator

Below is the calculator for you to calculate the weight of various metals. What you need to do is calculate the sectional area and find the metal density.

You can also refer to:

From the above two posts, you will find the density of various metals and alloys.




However, sometimes you may want to learn the weight calculation formula and keep it in your mind, here is it:

Weight (kg) = Sectional Area (mm2) × Length (m) × Density (ρ, g/cm3)× 1/1000

In order to help you quickly find the metal weight formula, I made infographic which is not only practical but also beautiful. (To the bottom)

Besides, recently I’m working on making steel weight chart in order to help the one who needs it. However, when I finished it, I find the steel weight calculation formula is much more convenient and accurate than the steel weight table.

P.S: You can click to check out the H Beam & I Beam Weight Calculator (Weight Chart in Kg).

    These formulas are correct. The formulas are easily derived through the equation m=pv

    “m” is the mass of the object.
    V is what you have to calculate as the volume.
    p is the density.

    The website is simplifying this formula into situation specific equations which can be derived from common variables you might know.

      this formula is one simple way to calculate rebar weight based on experience. You can also calculate based on the round steel weight calculation formula above.
