Aluminium Weight Calculator
This tool helps you quickly calculate how much a piece of aluminium weighs based on its shape, size, and type (alloy). It’s perfect for DIY projects, engineering work, or just checking material needs before buying.
How to Use This Tool
- Select your unit system
Choose between metric (meters, kilograms) or imperial (inches, pounds). - Pick the type of aluminium alloy
You can choose from common alloys like 1050, 1100, 6063, 7075, or just use average aluminum density. - Select your shape
Choose the shape that matches your object — whether it’s a flat plate, tube, wire, sphere, can, or even other shapes with known volume. - Enter dimensions
Fill in the exact measurements depending on the shape (like length, width, radius, thickness, etc.). - Set how many pieces you want to calculate for
You can enter any number — even just one piece or dozens. - Press “Calculate Weight”
The tool instantly gives you total weight in your chosen unit.
What the Tool Calculates
The calculator computes the volume of your shape based on its geometry, then multiplies it by the density of the selected alloy to find total weight.
- For example: a rectangular plate (like a sheet) uses length × width × thickness.
- A tube or ring uses outer radius minus inner radius squared times length.
- A wire is just circular cross-section area times length.
- A can calculates volume as the sum of body, base, and lid parts if included.
You don’t need to know complex formulas — we handle them for you. Just input your data.
What You Can Input
Here’s what each shape requires:
Rectangular Prism (Plate)
- Length: in meters or inches
- Width: in meters or inches
- Thickness: in meters or inches
Circular Prism
- Radius: in meters or inches
- Thickness: in meters or inches
Hexagonal Prism
- Side length: in meters or inches
- Thickness: in meters or inches
Octagonal Prism
- Side length: in meters or inches
- Thickness: in meters or inches
Ring Prism / Tube
- Outer radius (R): in meters or inches
- Inner radius (r): in meters or inches
- Length/thickness: in meters or inches
Wire
- Length: in meters or inches
- Radius: in meters or inches
Sphere
- Radius: in meters or inches
Can
- Height of can body: in meters or inches
- Inner radius (r): in meters or inches
- Outer radius (R): in meters or inches
- Base height and lid height if applicable
Other Prism
- Use this when you already know the volume — just enter it.
Tips for Accuracy
- Make sure all measurements are entered correctly.
- Always use consistent units (e.g., all in metric or all in imperial).
- If your shape is not listed, pick “Other” and input its volume directly.
Why This Tool Is Useful
It’s ideal if you’re:
- Building a project using aluminium
- planning to buy raw material
- checking how much it will weigh before cutting or welding
This tool saves time and avoids guesswork. No need to memorise formulas — just enter your shape and dimensions, and get accurate results every time.
Shape Descriptions
- Rectangular Prism (Plate): A flat rectangular block. Measured by length, width, and thickness.
- Circular Prism: Like a cylinder — circular cross-section with height (thickness).
- Hexagonal Prism: A six-sided solid, often used in structural bars or rods.
- Octagonal Prism: An eight-sided shape — common for some beams or decorative pieces.
- Ring Prism / Tube: Hollow ring-shaped object. Use outer and inner radius to calculate volume.
- Wire: Thin rod with circular cross-section. Length and radius matter here.
- Sphere: A solid ball — only need radius.
- Can: A container like a can, including base and lid if present.
- Other Prism: When you already know the total volume (e.g., from a mold or design).
Final Notes
This calculator works for any standard aluminium shape — no 3D modeling needed. Just input your measurements and get reliable weight results.
Whether you’re working with sheets, tubes, wires, or custom shapes, this tool adapts to your needs.
