How to convert megohms to milliohms
mΩ = MΩ × 1,000,000,000Multiply the value in megohms by 1,000,000,000. To go the other way, multiply by 1×10⁻⁹ (or divide by 1,000,000,000).
A megohm is larger than a milliohm: one megohm contains 1,000,000,000 milliohms.

About the units
Megohm (MΩ)
The megohm (MΩ) is a unit of electric resistance in the International System of Units (SI). One megohm equals 1,000,000 ohms (Ω).
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 megohm?
There are 1,000,000,000 milliohms in one megohm, and this value is exact by definition.
How do I convert megohms to milliohms?
Multiply the number of megohms by 1,000,000,000. For example, 10 MΩ × 1,000,000,000 = 10,000,000,000 mΩ.
How many megohms are in one milliohm?
One milliohm equals 1×10⁻⁹ megohms. That is the reverse factor, 1 ÷ 1,000,000,000.
What is 10 megohms in milliohms?
10 MΩ = 10,000,000,000 mΩ.
Is this MΩ 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.
