How the formula works
Both attoohm and femtoohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attoohms by 0.001 to get femtoohms. To reverse the conversion, multiply a femtoohm value by 1000 to get back to attoohms.
Frequently asked questions
What is Attoohm (aΩ)?
An Attoohm (aΩ) equals 1e-18 ohm(s), a scaled unit of electrical resistance used for atto-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 attoohms to femtoohms?
Multiply the attoohm value by 0.001 to get the equivalent in femtoohms. For example, 5 aΩ × 0.001 = 0.005 fΩ.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.001 is an exact, non-rounded value.
Can I convert femtoohms back to attoohms?
Yes. Divide the femtoohm value by 0.001, or multiply it by 1000, to get attoohms.
