Total Weight vs Bar Diameter
Formula
## Steel Bar Weight Calculation Steel weight is calculated from the cross-sectional area, length, and density. ### Formula **Weight per metre = (pi/4) x D^2 x rho** where D is the bar diameter in metres and rho is steel density (7850 kg/m^3). ### Quick Formula **Weight (kg/m) = D^2 / 162** (where D is in mm) This handy shortcut comes from simplifying pi/4 x (D/1000)^2 x 7850.
Esempio Risolto
100 metres of 12 mm diameter rebar.
- 01Weight per metre = pi/4 x (0.012)^2 x 7850 = 0.888 kg/m
- 02Quick check: 12^2 / 162 = 144/162 = 0.889 kg/m
- 03Total weight = 0.888 x 100 = 88.8 kg
