About
In engineering and fabrication, accurately estimating material weight is crucial for logistics, structural support calculations, and cost estimation. Raw steel is sold by weight, not just dimensions. A miscalculation here can lead to overloaded transport vehicles or significant budget overruns.
This tool provides a precise weight calculation for common stock shapes including plates, round bars, and tubes. Unlike generic calculators, it includes a material library for Stainless Steel, Aluminum, and Brass, accounting for the specific density variations of each alloy. The integrated "Project Bin" allows you to add multiple distinct cuts to a list, simulating a complete purchase order or bill of materials.
Formulas
Weight is derived from volume multiplied by the material's density.
General Formula:
Mass = Volume × Density
Plate Volume:
V = Length × Width × Thickness
Round Bar Volume:
V = π × r2 × Length
Hollow Tube Volume:
V = π × (R2 − r2) × Length
