Metal Plate Weight Calculator

Enter the length, width, and thickness of a metal plate and it returns the weight using the material's density. It covers carbon steel, stainless 304 and 316, aluminum 6061, copper, brass, and cast iron.

How to use
  1. Pick the material so the right density is applied.
  2. Enter the plate length, width, and thickness.
Estimates only, allow for waste and confirm against local building codes and supplier specs.

Common questions

How do I calculate the weight of a steel plate?

Multiply length by width by thickness to get the volume, then multiply by the density (about 0.284 lb/in³ for carbon steel). The calculator does this once you enter the dimensions.

Does stainless steel weigh the same as carbon steel?

Almost. Stainless 304 and 316 are close to carbon steel in density, so the same plate weighs only marginally more.
