The solid round iron and shaft weight are calculated by the cross-sectional area (π × d² ÷ 4) × density. You can calculate for steel, stainless steel (304, 316), aluminum, copper, brass, bronze, cast iron and other metals, and enter the density yourself for the material that is not in the list.
Formula
Meter weight (kg/m) = π × d² ÷ 4 × Density ÷ 1000
Example
The meter weight of the Ø20 mm steel shaft is 2.47 kg/m.
