Steel Weight Calculator

This calculator works out what a length of metal section weighs from its shape, its size and the density of the material. Pick round bar, square or hex bar, flat bar and plate, pipe, square or rectangular tube, angle, or an I or H beam, enter the dimensions in inches or millimetres along with the length and how many pieces you need, and choose a material or type in your own density. It returns the cross section area, the weight per foot and per metre, the weight of one piece and the total for the order. Rolled shapes are calculated with square corners, so the result names where a published mill table will read a little heavier or lighter and why.

Solid round stock. Enter the diameter in inches, or in millimetres if you switch the unit selector.

The outside diameter of the solid bar.

An I or H section built from two flanges and a web. For a channel, enter the flange width once and it is counted twice, which is how a C section is shaped too.

The full height of the section, outside to outside.
