25 lip 2024 · Our wire resistance calculator uses the following resistance formula: R = ρ × L / A. where: R — Resistance in Ω; ρ — Resistivity of material in Ω × m; L — Length of the wire; and; A — Cross-sectional area of the wire. You can use this wire resistance calculator to estimate conductance too, since: G = σ × A / L. where:
