How to convert milliohms to ohms
Ω = mΩ × 0.001Multiply the value in milliohms by 0.001. To go the other way, multiply by 1,000 (or divide by 0.001).
A milliohm is smaller than an ohm: it takes 1,000 milliohms to make one ohm.

About the units
Milliohm (mΩ)
The milliohm (mΩ) is a unit of electric resistance in the International System of Units (SI). One milliohm equals 0.001 ohms (Ω).
Ohm (Ω)
One volt per ampere.
Frequently asked questions
How many ohms are in one milliohm?
There are 0.001 ohms in one milliohm, and this value is exact by definition.
How do I convert milliohms to ohms?
Multiply the number of milliohms by 0.001. For example, 10 mΩ × 0.001 = 0.01 Ω.
How many milliohms are in one ohm?
One ohm equals 1,000 milliohms. That is the reverse factor, 1 ÷ 0.001.
What is 10 milliohms in ohms?
10 mΩ = 0.01 Ω.
Is this mΩ to Ω converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
