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 stepbystep 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
 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

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

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}.
 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:
V = Volume
L = The length of the aluminum sheet
W = The width of the aluminum sheet
T = The aluminum sheet’s thickness
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/m^{3} 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 = 0.05m^{3}
3003 Aluminum Alloy Density = 2730 kg/m^{3}
If we multiply the 0.05^{3} volume figure by the 2730 kg/m^{3} 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:
V = Volume
L = The length of the aluminum plate
W = The width of the aluminum plate
T = The aluminum plate’s thickness
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 a steel bar, the equation consists of the following elements:
V = Volume
π = Pi, or 3.142
r = The radius of the aluminum bar, squared
l = The length of the aluminum bar
Let’s work through an example of a 3003 aluminum alloy round bar that has a diameter of 40mm and a length of 2meters.
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/m^{3} (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 2meters, 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 = 0.0012568m^{3}
3003 Aluminum Alloy Density = 2730 kg/m^{3}
If we multiply the 0.0012568m^{3} volume figure by the 2730 kg/m^{3} density figure, we end up with a weight of 3.43 kg or 7.56 lbs.
