How the formula works
Both megaohm and milliohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in megaohms by 1.000000e+09 to get milliohms. To reverse the conversion, multiply a milliohm value by 1.000000e-09 to get back to megaohms.
Frequently asked questions
What is Megaohm (MΩ)?
A Megaohm (MΩ) equals 1e+6 ohm(s), a scaled unit of electrical resistance used for mega-scale electrical work.
What is Milliohm (mΩ)?
A Milliohm (mΩ) equals 1/1,000 ohm(s), a scaled unit of electrical resistance used for milli-scale electrical work.
How do I convert megaohms to milliohms?
Multiply the megaohm value by 1.000000e+09 to get the equivalent in milliohms. For example, 5 MΩ × 1.000000e+09 = 5.000000e+09 mΩ.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+09 is an exact, non-rounded value.
Can I convert milliohms back to megaohms?
Yes. Divide the milliohm value by 1.000000e+09, or multiply it by 1.000000e-09, to get megaohms.
