How the formula works
Both milliohm and ronnaohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in milliohms by 1.000000e-30 to get ronnaohms. To reverse the conversion, multiply a ronnaohm value by 1.000000e+30 to get back to milliohms.
Frequently asked questions
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.
What is Ronnaohm (RΩ)?
A Ronnaohm (RΩ) equals 1e+27 ohm(s), a scaled unit of electrical resistance used for ronna-scale electrical work.
How do I convert milliohms to ronnaohms?
Multiply the milliohm value by 1.000000e-30 to get the equivalent in ronnaohms. For example, 5 mΩ × 1.000000e-30 = 5.000000e-30 RΩ.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-30 is an exact, non-rounded value.
Can I convert ronnaohms back to milliohms?
Yes. Divide the ronnaohm value by 1.000000e-30, or multiply it by 1.000000e+30, to get milliohms.
