How the formula works
Both ronnahenry and femtohenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in ronnahenrys by 1.000000e+42 to get femtohenrys. To reverse the conversion, multiply a femtohenry value by 1.000000e-42 to get back to ronnahenrys.
Frequently asked questions
What is Ronnahenry (RH)?
A Ronnahenry (RH) equals 1e+27 henry(s), a scaled unit of inductance used for ronna-scale electrical work.
What is Femtohenry (fH)?
A Femtohenry (fH) equals 1e-15 henry(s), a scaled unit of inductance used for femto-scale electrical work.
How do I convert ronnahenrys to femtohenrys?
Multiply the ronnahenry value by 1.000000e+42 to get the equivalent in femtohenrys. For example, 5 RH × 1.000000e+42 = 5.000000e+42 fH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+42 is an exact, non-rounded value.
Can I convert femtohenrys back to ronnahenrys?
Yes. Divide the femtohenry value by 1.000000e+42, or multiply it by 1.000000e-42, to get ronnahenrys.
