Metal Weight Calculator

Metal gets heavy, and whether you want to see how much shipping is likely to be, or if your vehicle (or back) can handle it, it’s good to know what your order weighs. To help with that, we’ve got our handy weight calculator here. Fill out the information below and it will tell you how heavy that piece of material is.

How to Calculate Metal Weight

Whether you use the metal weight calculator above or calculate it manually, the formula is simple: weight = volume × density.

To calculate volume, multiply the material’s dimensions, then multiply that result by the material’s density.

Example:

To calculate the weight of a 3/16" thick × 4' × 8' steel plate, first find the volume:

48 × 96 × 0.1875 = total cubic inches

Then multiply by the density of steel (0.282 lb/in³):

48 × 96 × 0.1875 × 0.282 = ~250 lbs
