Metal Weight by Shape and Alloy
Weight per piece and total by shape, dimensions, length, and alloy density.
Formula and source
weight = cross-sectional area * length * density * quantity. Per-shape area from geometry: tube = pi/4 * (OD^2 - ID^2), hex = 0.866 * width^2, round = pi/4 * dia^2, etc. lb to kg via x 0.453592.
First-principles weight = volume x density. Densities are the published nominal values for the common alloys (carbon steel 0.2836, stainless 0.289, aluminum 6061 0.098, copper 0.323, brass 0.307 lb/in^3) or user-supplied.
