Disclaimer: The weights shown in the above calculator are for guidance only and should not form the basis of any calculations where precise or accurate information is required. It isn’t uncommon for theoretical metal weights and densities to vary considerably from actual weights and densities, for example, due to differences in manufacturing processes and material compositions. Therefore, you should obtain relevant, accurate information from manufacturers if exact weight calculations are required.

    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 average industry figures for each material. If you’re using a specific type of material and you know the density, we’d recommend using the real-life figure in your calculation to produce more accurate results.

  3. You can include multiple units of your chosen profile type in your calculation by changing the figure in the ‘Quantity’ input in box (2).
  4. Depending on the material profile you are using in your calculation, you’ll need to enter various dimensions, for example, ‘Length’, ‘Width’, ‘Diameter’, ‘Thickness’, or ‘Height’ to name a few.

    The calculator is programmed to automatically reformat depending on your chosen material profile, so you’ll only see the relevant dimensions for your particular calculation/material profile type.

    The calculator supports several unit types from metric millimeters to imperial feet, and you can choose these using the ‘Unit’ dropdown beside each dimension input field.

How to Calculate Material Weight

The easiest way to calculate material weight is using our handy calculator above.

If you’d prefer to calculate a material’s weight manually though, you can do so via the following equation:

Weight = Material Volume x Material Density

This equation remains the same whether you’re working with metric units, such as millimeters, or imperial units, such as feet.

As shown in the formula, the first step is to find the volume of the material in question. For basic shapes, for example, cubes or sheets, this should be relatively simple, but it might be trickier for more complex profiles such as hexagonal plates or beams.

You can calculate the volume via the following equation:

Volume = Area x Length

The final input is the density of the material in question, which you can define as the material’s ‘mass per unit volume,’ or essentially, how heavy the material is for a given size.

When it comes to density, these figures are readily available for various materials, and we’ve included tables with the density data for a wide variety of materials below.

Let’s look at a real-life example to show you step-by-step how to calculate a material’s weight:

How to Calculate the Weight of a Concrete Slab

When it comes to calculating the weight of our concrete slab, there are a few dimensions that we’re interested in as shown in this diagram:

material weight calculator example image - slab dimension example

Whereby:

L = The length of the concrete slab

W = The width of the concrete slab

T = The concrete slab’s thickness

We’re also interested in the density of the concrete slab, but we’ll focus on the dimensions only for now.

For this example, let’s assume the following dimensions for our concrete slab:

  • Length: 2m
  • Width: 1m
  • Thickness: 0.1m

The first step is to determine the volume of the concrete slab, and we’ll get this by multiplying the cross-sectional area by the slab’s length, as mentioned above.

1) To get the area, we’ll multiply the slab’s width by its thickness as per the following equation:

Area = Width x Thickness
Area = 1m x 0.1m
Area = 0.1m2

2) Now that we have the slab’s cross-sectional area, we can calculate its overall volume using the following equation:

Volume = Area x Length
Volume = 0.1m2 x 2m
Volume = 0.2m3

3) The final step is to multiply the slab’s volume by the density of concrete to find the overall weight. We’ll use a density of 2300kg/m3 for the concrete in our calculation as follows:

Weight = Volume x Density
Weight = 0.2m3 x 2300kg/m3
Weight = 460kg

As shown, multiplying the volume figure we’ve just calculated by the known typical density of concrete gives us a final weight of 460kg for our concrete slab.
