All resistance conversions use Ohms (Ω) as the base unit.
Metric prefixes:
- 1 Ω = 1,000 mΩ (milliohms)
- 1 kΩ = 1,000 Ω (kilohms)
- 1 MΩ = 1,000,000 Ω (megohms)
Ohm’s Law:
- Resistance = Voltage / Current (R = V / I)
Common references:
- Copper wire (1m, 1mm²): about 0.017 Ω
- Typical resistor: 100 Ω to 10 kΩ
- Human body (dry skin): 1–100 kΩ
