How the formula works
Both megaohm and femtoohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in megaohms by 1.000000e+21 to get femtoohms. To reverse the conversion, multiply a femtoohm value by 1.000000e-21 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 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 megaohms to femtoohms?
Multiply the megaohm value by 1.000000e+21 to get the equivalent in femtoohms. For example, 5 MΩ × 1.000000e+21 = 5.000000e+21 fΩ.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+21 is an exact, non-rounded value.
Can I convert femtoohms back to megaohms?
Yes. Divide the femtoohm value by 1.000000e+21, or multiply it by 1.000000e-21, to get megaohms.
