Wire Length

Round Wire

ft/lb = .1061 ÷ ρ x D²

Where ρ = alloy density in lb/in3, and D = wire diameter in inches.

m/kg = 1273.24 ÷ ρ x D²

Where ρ = alloy density in gm/cm3, and D = wire diameter in mm.

Square or Rectangular Wire

ft/lb = .0833 ÷ ρ (w x t – .8584R²)

Where ρ = alloy density in lb/in3, w = wire length in inches, t = wire thickness in inches, and R = corner radius in inches.

m/kg = 1000 ÷ ρ (w x t – .8584R²)

Where ρ = alloy density in gm/cm3, w = wire length in mm, t = wire thickness in mm, and R = corner radius in mm.

Round Edge Flat Wire

ft/lb = .0833 ÷ ρ x w x t x C_f

Where ρ = alloy density in lb/in3, w = wire width in inches, t = wire thickness in inches, and Cf = correction factor.

m/kg = 1000 ÷ ρ x w x t x C_f

Where ρ = alloy density in gm/cm3, w = wire width in mm, t = wire thickness in mm, and Cf = correction factor.
