How to Use the Angle Weight Calculator

1. Use the ‘Select an Angle Type’ dropdown to choose the profile type that you’d like to calculate the weight of, with both equal and unequal angle profiles being available.

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

   The ‘Density’ box will automatically be populated based on the material type you choose.

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

3. Use the ‘Quantity’ box to specify how many angle units you’d like to include in the calculation.

4. Depending on the angle profile chosen, you’ll need to enter various dimensions, for example, ‘Length’, ‘Width’, ‘Height’, and ‘Thickness’.

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

   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.

How to Calculate Angle Weight

Don’t feel like using our handy angle weight calculator? Here’s how to manually calculate the weight of both equal and unequal angles:

How to Calculate the Weight of Equal Angle

The first step is to determine the volume of the equal angle, with the equation as follows:

When calculating the weight of equal angle stock, the equation consists of the following elements:

The equation above basically splits the angle stock into two separate sections, the lower width portion and the upper height portion, which we calculate the volume of separately before adding these together.

Let’s work through an example of a mild steel angle that has a length of 1m, a width and height of 100mm, and a thickness of 10mm.

Because we’re using a density of 7850 kg/m³ (the density of mild steel) for the calculation, we’ll need to convert the dimensions in this example to meters.

The length of the angle stock is already in meters, so we don’t need to change this, but the 100mm width and height should be 0.1 (these dimensions converted to meters), and the 10mm thickness becomes 0.01.

Here’s how the calculation works:

Volume = (0.1 x 0.01 x 1) + ((0.1 – 0.01) x 0.01 x 1)
Volume = 0.0019³

MS Angle Weight Calculator Density Figure = 7850 kg/m³ (see above calculator)

If we multiply the 0.0019³ volume figure by the 7850 kg/m³ density figure, we end up with a weight of 14.92 kg or 32.88 lbs.

How to Calculate the Weight of Unequal Angle

As with an equal angle, the first step is to determine the volume of the unequal angle you want to calculate the weight of.

The equation is as follows:

Although it might look confusing, the equation is relatively simple and consists of the following elements:

The equation above basically splits the unequal angle stock into two separate sections, the lower width portion and the upper height portion, and we calculate the volume of these separately before adding the values together.

Let’s work through an example of an unequal mild steel angle that has a length of 2m, a width of 200mm, a height of 100mm, and a thickness of 15mm.

Because we’re using a density of 7850 kg/m³ for the calculation, we’ll need to convert the dimensions in this example to meters.

The length of the unequal angle stock is already in meters, so we don’t need to change this, but the 200mm width should be 0.2 (the width dimension converted to meters), the 100mm height should be 0.1, and the 15mm thickness becomes 0.015.

Here’s how the calculation works:

Volume = (0.2 x 0.015 x 2) + ((0.1 – 0.015) x 0.015 x 2)
Volume = 0.00855³

Mild Steel Density = 7850 kg/m³

If we multiply the 0.00855³ volume figure by the 7850 kg/m³ density figure, we end up with a weight of 67.80 kg or 149.48 lbs.
