Electrical Resistance conversion family
Electrical Resistance unit conversions
Electrical resistance uses the ohm (Ω), the coherent SI derived unit equal to volt per ampere.
Five named units
Unit and factor reference
| Unit | Symbol | Factor to base | Relationship | Definition and variant |
|---|---|---|---|---|
| ohm | Ω | 1 | defined | The ohm is the coherent SI derived unit of electrical resistance: 1 Ω = 1 V/A. Named variant: Scalar electrical resistance. The base factor is exactly 1 by the family base-unit choice. |
| milliohm | mΩ | 0.001 | exact | A milliohm is the SI decimal submultiple formed by applying milli (10^-3) to ohm: 1 mΩ = 0.001 Ω. Named variant: Scalar electrical resistance. The decimal-prefix relationship is exact. |
| kiloohm | kΩ | 1000 | exact | A kiloohm is the SI decimal multiple formed by applying kilo (10^3) to ohm: 1 kΩ = 1000 Ω. Named variant: Scalar electrical resistance. The decimal-prefix relationship is exact. |
| megaohm | MΩ | 1000000 | exact | A megaohm is the SI decimal multiple formed by applying mega (10^6) to ohm: 1 MΩ = 1000000 Ω. Named variant: Scalar electrical resistance. The decimal-prefix relationship is exact. |
| gigaohm | GΩ | 1000000000 | exact | A gigaohm is the SI decimal multiple formed by applying giga (10^9) to ohm: 1 GΩ = 1000000000 Ω. Named variant: Scalar electrical resistance. The decimal-prefix relationship is exact. |

Evidence and review status
This family is machine-reviewed-pending-human. Automated checks verify structure, factor parity and source references; they do not constitute human or specialist approval.
Family assumptions and limits
- This converter treats resistance as a non-negative scalar magnitude; signed differential resistance and active-device model parameters are outside scope.
- Unit conversion does not model temperature coefficient, tolerance, frequency dependence, reactance, or complex impedance.
- The ohm symbol is Greek capital omega (Ω), not the Latin letter O or the numeral zero.
- A conversion does not add significant figures to the source measurement.
