How the formula works
Both femtoohm and ohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtoohms by 1.000000e-15 to get ohms. To reverse the conversion, multiply a ohm value by 1.000000e+15 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 Ohm (Ω)?
The ohm (Ω) is the SI unit of electrical resistance, describing how strongly a material opposes current flow.
How do I convert femtoohms to ohms?
Multiply the femtoohm value by 1.000000e-15 to get the equivalent in ohms. For example, 5 fΩ × 1.000000e-15 = 5.000000e-15 Ω.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-15 is an exact, non-rounded value.
Can I convert ohms back to femtoohms?
Yes. Divide the ohm value by 1.000000e-15, or multiply it by 1.000000e+15, to get femtoohms.
