How the formula works
Both milliohm and femtoohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in milliohms by 1.000000e+12 to get femtoohms. To reverse the conversion, multiply a femtoohm value by 1.000000e-12 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 Femtoohm (fΩ)?
A Femtoohm (fΩ) equals 1e-15 ohm(s), a scaled unit of electrical resistance used for femto-scale electrical work.
How do I convert milliohms to femtoohms?
Multiply the milliohm value by 1.000000e+12 to get the equivalent in femtoohms. For example, 5 mΩ × 1.000000e+12 = 5.000000e+12 fΩ.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+12 is an exact, non-rounded value.
Can I convert femtoohms back to milliohms?
Yes. Divide the femtoohm value by 1.000000e+12, or multiply it by 1.000000e-12, to get milliohms.
