Aluminium Weight Calculator
Calculate the weight of aluminium (aluminum) sheet, plate, bar, pipe, tube and sections in kg or lb. Choose the grade, the shape and the sizes; the result updates as you type.
Theoretical weight from nominal sizes. Actual weight varies with mill tolerance and, for rolled angles, channels and beams, the corner radius. Steel price in the UAE today: see the current price per ton.
Aluminium weight formula
Weight (kg) = cross-section area (mm²) × length (m) × 2.70 ÷ 1000, using 2.70 g/cm³ for 6061. For sheet, that is length (m) × width (m) × thickness (mm) × 2.70.
Example: a 1220 × 2440 × 2 mm aluminium sheet weighs 1.22 × 2.44 × 2 × 2.70 = 16.07 kg. The same sheet in steel would weigh about 2.9 times as much.
Aluminium is about one third the weight of steel
Aluminium’s density is 2.70 g/cm³ against 7.85 g/cm³ for mild steel, a ratio of 0.34. To convert a steel weight to aluminium, multiply by 0.344; to convert aluminium to steel, multiply by 2.9.

Aluminium grades and densities
Grades differ slightly in density, which changes the weight by up to 4%.
| Grade | Density (g/cm³) | Typical use |
|---|---|---|
| 1100 | 2.71 | Sheet, foil, cladding |
| 2024 | 2.78 | Aircraft parts, high strength |
| 5052 | 2.68 | Marine sheet, tanks, chequered plate |
| 6061 | 2.70 | Structural bar, plate, machined parts |
| 6063 | 2.69 | Architectural extrusions, windows, tube |
| 7075 | 2.81 | High-strength aerospace parts |

Frequently asked questions
How do I calculate aluminium sheet weight?
Multiply length (m) × width (m) × thickness (mm) × 2.70. A 1220 × 2440 × 2 mm sheet weighs 16.07 kg.
What is the density of aluminium?
About 2.70 g/cm³ (2,700 kg/m³) for 6061. Other grades range from 2.68 (5052) to 2.81 (7075).
How much lighter is aluminium than steel?
Aluminium weighs about 0.34 times as much as mild steel for the same size, roughly one third.
What is the weight of a 25 mm aluminium round bar per metre?
About 1.33 kg/m in grade 6061.
Is aluminium and aluminum the same?
Yes. Aluminium is the British and international spelling and aluminum the American spelling of the same metal.
