Milliohm quick reference
| Milliohm | Ohm | Kiloohm | Microohm |
|---|---|---|---|
| 1 mΩ | = 0.001 Ω | = 0.000001 kΩ | = 1000 µΩ |
| 10 mΩ | = 0.01 Ω | = 0.00001 kΩ | = 10000 µΩ |
| 100 mΩ | = 0.1 Ω | = 0.0001 kΩ | = 100000 µΩ |
| 1000 mΩ | = 1 Ω | = 0.001 kΩ | = 1000000 µΩ |
Where the milliohm fits
The next smaller electric resistance unit is the microohm (µΩ). 1 mΩ = 1000 µΩ, and 1 µΩ = 0.001 mΩ.
The next larger electric resistance unit is the ohm (Ω). 1 mΩ = 0.001 Ω, and 1 Ω = 1000 mΩ.
