Aluminum Weight Calculator

From sheets to round bar stock, this handy aluminum weight calculator makes it easy to calculate the weight of various aluminum profiles.

For technical guidance, please refer to the user guide below the calculator.

We’ve included a series of helpful step-by-step guides below the calculator to show you the process of calculating the weight of various aluminum profiles if you want to calculate these manually. You’ll also find a handy reference table showing the typical densities of different grades of aluminum at the end of this article.

How to Use the Aluminum Weight Calculator

1. Use the ‘Select a Aluminum Profile’ dropdown to choose the profile type that you’d like to calculate the weight of, with the following aluminum profile types being available:
• Sheet / Rectangular Plate
• Square Plate
• Round Plate
• Ring Plate
• Hexagonal Plate
• Octagonal Plate
• Round Bar
• Square Bar
• Rectangular Bar
• Hexagonal Bar
• Pipe / Round Tube
• Square Tube
• Rectangular Tube
• Equal Angle
• Unequal Angle
• Tee
• Can (With Lid)
• Can (Without Lid)
• Sphere

2. Use the ‘Material’ dropdown in box (2) to choose the grade of aluminum for your selected profile.

   The ‘Density’ box will automatically be populated based on the grade of aluminum you choose.

   You can update the ‘Density’ figure if needed, although this is based on industry guidance for each grade of aluminum.

3. Use the ‘Quantity’ box to specify how many units you’d like to include of your selected profile in the calculation.

4. Depending on the aluminum profile chosen, you’ll need to enter various dimensions, for example, ‘Length’, ‘Width’, ‘Height’, ‘Diameter’, or ‘Thickness’ to name a few.

   The calculator will automatically reformat depending on the aluminum profile type chosen, meaning only the relevant dimensions will be shown.

   Any missed dimensions will be highlighted when you click the ‘Calculate’ button, meaning you can go back and include these to complete your calculation.

   You can select the relevant units for each measurement using the ‘Unit’ dropdowns.

   Note: If you choose ‘inch’ as a unit, you’ll need to use either whole or decimal numbers instead of fractions. For example, 0.25 instead of ¹/₄.

5. Use the ‘Calculate’ button to complete the calculation, and the ‘Reset’ button to reset the aluminum weight calculator.

How to Calculate the Weight of Aluminum

Don’t feel like using the aluminum weight calculator above? Here’s how to manually calculate the weight of a variety of common aluminum profile types:

How to Calculate the Weight of Aluminum Sheet

You’ll first need to calculate the volume of the aluminum sheet using the following equation:

Here’s a summary of the various elements of the equation:

Let’s work through an example of an aluminum sheet with the following attributes:

• Material Grade – 3003 aluminum alloy (the most widely used type)
• Length – 2m
• Width – 1m
• Thickness – 25mm

Because we’re using a density of 2730 kg/m³ for the calculation, we’ll need to convert the dimensions in this example to meters. The length and width of the sheet are already in meters, so we don’t need to change these, but the 25mm thickness should be 0.025 (the width dimension converted to meters).

Here’s how the calculation works:

Volume = 2 x 1 x 0.025
Volume = 0.05m³

3003 Aluminum Alloy Density = 2730 kg/m³

If we multiply the 0.05³ volume figure by the 2730 kg/m³ density figure, we end up with a weight of 136.50 kg or 300.93 lbs.

How to Calculate the Weight of Aluminum Plate

You can work out the weight of aluminum plate (in either square or rectangular form) by following the same process outlined above for calculating the weight of an aluminum sheet.

The same formula is used to first determine the volume of the aluminum plate:

The formula consists of the following elements:

We’ve shown a worked example of this equation in the section above.

How to Calculate the Weight of an Aluminum Bar (Round)

First we need to calculate the volume of the aluminum bar, with the equation as follows for round bar stock:

When calculating the weight of an aluminum bar, the equation consists of the following elements:

Let’s work through an example of a 3003 aluminum alloy round bar that has a diameter of 40mm and a length of 2-meters.

In this case, we’ll be multiplying the Pi figure (3.142) by the radius squared (20mm for this example, or half the diameter value), and finally, we’ll be multiplying by the length of the aluminum round bar (2m).

Because we’re using a density of 2730 kg/m³ (the density of 3003 aluminum alloy) for the calculation, we’ll need to convert the dimensions in this example to meters.

The length of the bar is already 2-meters, so we don’t need to change this, but the 20mm radius should be 0.020 (the radius dimension converted to meters).

Here’s how the calculation works:

Volume = (3.142 x (0.020 x 0.020)) x 1
Volume = 0.0012568m³

3003 Aluminum Alloy Density = 2730 kg/m³

If we multiply the 0.0012568m³ volume figure by the 2730 kg/m³ density figure, we end up with a weight of 3.43 kg or 7.56 lbs.
