Alu Weight Calculator
Aluminum is one of the most widely used engineering materials in the world because of its excellent strength-to-weight ratio, corrosion resistance, durability, and versatility. It is used in industries such as aerospace, automotive, construction, manufacturing, marine engineering, and home improvement. Whether you are fabricating machine parts, purchasing raw materials, or estimating shipping costs, knowing the exact weight of aluminum is essential.
Manually calculating aluminum weight can be confusing because different material shapes require different volume formulas. A sheet uses one formula, while a round bar, square bar, or pipe requires another. Additionally, unit conversions between millimeters, cubic centimeters, grams, and kilograms increase the chances of calculation errors.
The Alu Weight Calculator simplifies this entire process by automatically calculating the volume and weight of aluminum materials based on their dimensions. Simply select the material shape, enter the required measurements, and the calculator instantly provides accurate results using the standard aluminum density of 2.70 g/cm³.
This calculator is suitable for engineers, machinists, manufacturers, students, contractors, fabricators, metal suppliers, DIY enthusiasts, and anyone who regularly works with aluminum products.

Formula Used by the Alu Weight Calculator
The calculator follows a straightforward mathematical process.
Step 1: Calculate Volume
The volume depends on the selected shape.
Sheet / Plate
Formula
Volume = Length × Width × Thickness
Round Bar
Formula
Volume = π × (Diameter ÷ 2)² × Length
Square Bar
Formula
Volume = Side² × Length
Pipe / Tube
Formula
Volume = π × [(Outer Radius²) − (Inner Radius²)] × Length
Step 2: Convert Volume
The dimensions are entered in millimeters.
The calculator converts cubic millimeters into cubic centimeters.
Volume (cm³) = Volume (mm³) ÷ 1000
Step 3: Calculate Weight
The calculator uses the standard aluminum density:
Density = 2.70 g/cm³
Weight is calculated using:
Weight = Volume × Density
Finally, the result is converted into kilograms.
Example Calculation
Suppose you have an aluminum sheet with the following dimensions:
- Length = 1000 mm
- Width = 500 mm
- Thickness = 5 mm
Step 1
Volume
1000 × 500 × 5
= 2,500,000 mm³
Step 2
Convert to cubic centimeters
2,500,000 ÷ 1000
= 2500 cm³
Step 3
Calculate weight
2500 × 2.70
= 6750 grams
Convert to kilograms
6750 ÷ 1000
= 6.75 kg
Result:
- Volume: 2500 cm³
- Weight: 6.75 kg
Standard Aluminum Density
This calculator uses the commonly accepted density:
| Property | Value |
|---|---|
| Density | 2.70 g/cm³ |
| Equivalent | 2700 kg/m³ |
| Specific Gravity | 2.70 |
This value provides accurate estimates for most commercial aluminum alloys.
