  • Preparing electrical conductor resistance tables using AWG or kcmil sizing.
  • Calculating conductor resistance for power distribution designs using length in feet and area in circular mils.
  • Reporting soil or rock resistivity in geophysical studies.
  • Designing cables and overhead power lines requiring accurate resistivity unit conversions.

Tips & Best Practices

  • Always verify units before converting to ensure correct input and output selections.
  • Use the converted value in conjunction with conductor length and cross-sectional area to compute resistance.
  • Apply this conversion primarily within North American electrical contexts where circular mil ohm/foot is standard.
  • Account for temperature effects separately, as resistivity varies with temperature conditions.
  • Use precise measurements of cross-sectional area and geometry to improve calculation reliability.

Limitations

  • Conversion assumes constant temperature since resistivity changes with temperature.
  • Circular mil ohm/foot is mainly applicable within North American wiring and conductor standards.
  • Cross-sectional area and shape measurement accuracy affects the precision of resistance calculations.
