Key values (for reference)
ⓘ Assumptions
Uniform prismatic section and constant nominal density. Sharp corners; mill tolerances, coatings and cutouts excluded. Weight uses g = 9.80665 m/s².
Equations & calculation model
m = ρ × V
W = m × 9.80665 m/s²
Idealised calculations for preliminary design. Check geometry, loading and boundary conditions against your application.
What it is used for
Estimating stock mass and lifting or shipping weight from nominal geometry and density.
Standards & references
OpenStax University Physics: density and mass per volume. The mass model uses volume × density. Grade-specific density presets have not been individually verified against supplier certificates; they remain typical estimates. Use certified density and actual dimensions for critical weight calculations.
