Note: Standard spool sizes: 2 lb, 10 lb, 33 lb, 44 lb (20 kg). Drums: 500 lb, 1000 lb. Density for mild steel ER70S-6 wire is 0.283 lb/in3.

Reference

Wire Length = Spool Weight / (Wire Cross-Section Area x Wire Density) Area = pi x (d/2)^2 Steel wire density: 0.283 lb/in3 (7.85 g/cm3) Aluminum wire density: 0.098 lb/in3 (2.70 g/cm3) Stainless wire density: 0.289 lb/in3 (8.0 g/cm3) Weld Time = Wire Length / Wire Feed Speed
