Resistance of a Conductor Calculator

Calculate the electrical resistance of a round conductor with ease using this intuitive tool. Simply input the conductor's length, diameter, and conductivity (or select a common material like copper, silver, or aluminium), and the calculator will instantly compute the total resistance in ohms (Ω).

Key Features:

✅ Supports Multiple Units – Enter length and diameter in feet, meters, inches, miles, and more.
✅ Material Database – Choose from predefined conductivity values for common conductors (Copper, Silver, Gold, etc.).
✅ Precise Calculations – Uses the formula R=Lσ×AR=σ×AL​, where:

• RR = Resistance (Ω)
• LL = Length of the conductor (in meters)
• σσ = Conductivity (Siemens per meter, S/m)
• AA = Cross-sectional area (πr², where r is the radius)
  ✅ User-Friendly Design – Clean interface with a modern gradient background for a seamless experience.

Perfect for electrical engineers, students, and hobbyists working with wiring, circuits, or any conductive material.
