How to convert ohms to milliohms
mΩ = Ω × 1,000Multiply the value in ohms by 1,000. To go the other way, multiply by 0.001 (or divide by 1,000).
An ohm is larger than a milliohm: one ohm contains 1,000 milliohms.

About the units
Ohm (Ω)
One volt per ampere.
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).
Frequently asked questions
How many milliohms are in one ohm?
There are 1,000 milliohms in one ohm, and this value is exact by definition.
How do I convert ohms to milliohms?
Multiply the number of ohms by 1,000. For example, 10 Ω × 1,000 = 10,000 mΩ.
How many ohms are in one milliohm?
One milliohm equals 0.001 ohms. That is the reverse factor, 1 ÷ 1,000.
What is 10 ohms in milliohms?
10 Ω = 10,000 mΩ.
Is this Ω to mΩ 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.
