How the formula works
Both petahenry and femtohenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in petahenrys by 1.000000e+30 to get femtohenrys. To reverse the conversion, multiply a femtohenry value by 1.000000e-30 to get back to petahenrys.
Frequently asked questions
What is Petahenry (PH)?
A Petahenry (PH) equals 1e+15 henry(s), a scaled unit of inductance used for peta-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 petahenrys to femtohenrys?
Multiply the petahenry value by 1.000000e+30 to get the equivalent in femtohenrys. For example, 5 PH × 1.000000e+30 = 5.000000e+30 fH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+30 is an exact, non-rounded value.
Can I convert femtohenrys back to petahenrys?
Yes. Divide the femtohenry value by 1.000000e+30, or multiply it by 1.000000e-30, to get petahenrys.
