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

However, the weight calculation formula is writen in the calculator by the develpers, you still don’t know whether their formula is correct.

And sometimes, you want to learn the weight calculation formula and remember it in your mind.

In this case, the weight calculator is not suitable for you.

In order to help you quickly find the metal weight formula, I made below infographic which is not only pratical, but also beautiful.

If you want the PDF version of the weight calculation formula, you can save below infographic or bookmark in web browser.

**Steel Plate**

- Formula: 7.85×length (m)×width (m)×thickness (mm)
- E.g: 6m (length)×1.51m (width)×9.75mm (thickness)
- Calculation: 7.85×6×1.51×9.75=693.43kg

**Steel Tube**

- Formula: （OD-Wall thickness）×Wall thickness (mm)×0.02466×length (m)
- E.g: 114mm(OD)×4mm (Wall thickness) × 6m (length)
- Calculation: （114-4）×4×0.02466×6=65.102kg

You can also use Tube & Rod Weight Calculator to calculate the weight.

**Round Steel**

- Formula: Dia.mm×Dia.mm×0.00617×length (m)
- E.g: Φ20mm (Dia.)×6m (length)
- Calculation: 20×20×0.00617×6=14.808kg

**Square Steel**

- Formula: Edge width (mm)×Edge width (mm)×length (m)×0.00785
- E.g: 50mm (Edge width)×6m (length)
- Calculation: 50×50×6×0.00785=117.75(kg)

**Flat Steel**

- Formula: Edge width (mm)×thickness (mm)×length (m) × 0.00785
- E.g: 50mm (Edge width) × 5.0mm (thickness)×6m (length)
- Calculation: 50×5×6×0.00785=11.7.75(kg)

**Hexagonal Steel**

- Formula: Edge-to-edge Dia.×Edge-to-edge Dia.× length (m)×0.00068
- E.g: 50mm (Dia.) ×6m (length)
- Calculation: 50×50×6×0.0068=102(kg)

**Rebar**

- Formula: Dia.mm×Dia.mm×0.00617×length (m)
- E.g: Φ20mm(Dia.)×12m (length)
- Calculation: 20×20×0.00617×12=29.616kg

**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 (mm)×thickness×0.015×length (m)
- E.g: 50mm×50mm×5 thickness×6m(length)
- Calculation: 50×5×0.015×6=22.5kg

**Unequal-leg Angle Steel**

- Formula: (Edge width+Edge width) × thickness×0.0076×lengthm
- E.g: 100mm×80mm×8 thickness×6m(length)
- Calculation: (100+80) × 8×0.0076×6=65.67kg

Other nonferrous metals

**Brass Tube**

- Formula: (OD-Wall thickness) × thickness×0.0267×lengthm
- E.g: 20mm×1.5mm (thickness)×6m(length)
- Calculation: (20-1.5) × 1.5×0.0267×6=4.446kg

**Copper Tube**

- Formula: (OD-Wall thickness) × thickness×0.02796×length (m)
- E.g: 20mm×1.5mm (thickness)×6m(length)
- Calculation: (20-1.5) ×1.5×0.02796×6=4.655kg

**Aluminum Embossed Sheet**

- Formula: length (m)×width (m)×thickness (mm)×2.96
- E.g: 1m width×3m length×2.5mm thickness
- Calculation: 1×3×2.5×2.96=22.2kg

Brass Plate

Ratio: 8.5

Copper Sheet

Ratio: 8.9

Zinc Plate

Ratio: 7.2

Lead Plate

Ratio: 11.37

**Calculation Method**: ratio × thickness = weight / ㎡

**Calculation Method**: ratio × thickness = weight / ㎡

lekh2003January 3, 2018 at 4:00 pmThese 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.
