How to Calculate Metal Weight

You can find the weight of a metal object or material in a few simple steps.

Step One: Calculate the Volume of the Metal

The first step in finding the weight of a metal object is to find its volume. For a rectangular object such as a metal plate or bar, use the following volume formula:

volume = length × width × height

The volume is equal to the length times the width times the height.

When measuring the volume, it is essential to keep all dimensions in the same unit. So, you should measure the length, width, and height in only inches or only centimeters. The resulting volume will thus be in cubic inches or in cubic centimeters.

Use the following volume formulas for various metal shapes:

square bar:
width × width × length

round bar:
3.14 × (diameter ÷ 2) × (diameter ÷ 2) × length

square tubing:
(width – wall thickness) × wall thickness × 4 × length

round tubing:
(outer diameter – wall thickness) × wall thickness × 3.14 × length

plate/sheet:
width × thickness × length

Step Two: Find the Metal Density

The next step in calculating the weight is to find the density of the metal object. You’ll need to know what type of metal the object is, then reference a density chart to locate the density.

Use our metal density chart to locate the density of the metal you’re using. For instance, steel has a density of 490.1 lb/ft³.

Step Three: Multiply the Volume by the Density

Once you know the volume and the density, the final step is to multiply the volume by the density to calculate the weight.

weight = volume × density

Thus, the weight, or mass, of a metal object is equal to its volume multiplied by its density.
