How the formula works
Both femtoohm and attoohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtoohms by 1000 to get attoohms. To reverse the conversion, multiply a attoohm value by 0.001 to get back to femtoohms.
Frequently asked questions
What is Femtoohm (fΩ)?
A Femtoohm (fΩ) equals 1e-15 ohm(s), a scaled unit of electrical resistance used for femto-scale electrical work.
What is Attoohm (aΩ)?
An Attoohm (aΩ) equals 1e-18 ohm(s), a scaled unit of electrical resistance used for atto-scale electrical work.
How do I convert femtoohms to attoohms?
Multiply the femtoohm value by 1000 to get the equivalent in attoohms. For example, 5 fΩ × 1000 = 5000 aΩ.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1000 is an exact, non-rounded value.
Can I convert attoohms back to femtoohms?
Yes. Divide the attoohm value by 1000, or multiply it by 0.001, to get femtoohms.
