How is rebar weight calculated?

Weight = π(d/2)² × L × ρ, where d is diameter, L is length, ρ is density.

Why does pipe weight use hollow area?

Pipes are hollow; area = π(R_outer² - R_inner²).

Yes, select material; densities are: steel 7850, aluminum 2700, copper 8960 kg/m³.

Calculate weight of steel bars, rebars, pipes, and plates in kg and lb.

W = A \times L \times ρ, A = π r^{2} (bar), A = π (R_{o}^{2} - R_{i}^{2}) (pipe)
