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.
For the metal density, you can also refer to:
- Density Table of Metals (Iron, Steel, Brass, Aluminum) and Alloys
- Density Table for Commonly Used Sheet Metal Materials
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:
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)
P.S: Among all of the metal weight calculation formula in the following part, there are two kinds of metals that are not mentioned, which are I beam steel and H beam steel.
If you want to know the difference between H beam steel and I beam steel as well as the methods to calculate the weight of H beam steel and I beam steel, you will get the answers from the following two quick links:
- The Ultimate Difference Between H-beam And I-beam Steel
- H Beam & I Beam Weight Calculator (Weight Chart in Kg)
Theoretical Steel Weight Chart
If you want to get the weight of various metals from the chart, you can refer to the following page:

Flat Steel Tube
- Formula: (Edge length + Edge width) × 2 × thickness×0.00785×length (m)
- E.g: 100mm×50mm×5mm (thickness)×6m (length)
- Calculation: (100+50) × 2×5×0.00785×6=70.65kg
Rectangular Steel Tube
- Formula: Edgewidthmm×4×thickness×0.00785×length(m)
- E.g: 50mm×5mm (thickness)×6m (length)
- Calculation: 50×4×5×0.00785×6=47.1kg
Equal-leg angle Steel
- Formula: (Edge width×2-thickness)×thickness×0.00785×length (m)
- E.g: 50mm×50mm×5 thickness×6m(length)

Unequal-leg Angle Steel
- Formula: (Edge width+Edge width-thickness) × thickness×0.0076×lengthm
