1 Ω = 1000 mΩ
1 Ohm (Ω) = 1000 Milliohm (mΩ).
If you want to reverse convert, use Milliohm → Ohm. 1 mΩ = 0.001 Ω. You can also explore the full Electric Resistance converter page for more cross conversions.
Conversion formula
Ohm to Milliohm formula: value in mΩ = value in Ω × 1000.
Milliohm to Ohm formula: value in Ω = value in mΩ × 0.001.
How to convert Ohm to Milliohm
To convert Ohm to Milliohm, multiply the value in Ω by 1000. This gives the result in mΩ.
For example, 1 Ω = 1000 mΩ and 10 Ω = 10000 mΩ.
What is Ohm?
Ohm (Ω): Resistance corresponding to one volt per ampere. 1 Ω = 1 V/A.
What is Milliohm?
Milliohm (mΩ): Low contact, cable and shunt resistance. 1 mΩ = 0.001 Ω.
FAQ
