How the formula works
Both petahenry and ronnahenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in petahenrys by 1.000000e-12 to get ronnahenrys. To reverse the conversion, multiply a ronnahenry value by 1.000000e+12 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 Ronnahenry (RH)?
A Ronnahenry (RH) equals 1e+27 henry(s), a scaled unit of inductance used for ronna-scale electrical work.
How do I convert petahenrys to ronnahenrys?
Multiply the petahenry value by 1.000000e-12 to get the equivalent in ronnahenrys. For example, 5 PH × 1.000000e-12 = 5.000000e-12 RH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-12 is an exact, non-rounded value.
Can I convert ronnahenrys back to petahenrys?
Yes. Divide the ronnahenry value by 1.000000e-12, or multiply it by 1.000000e+12, to get petahenrys.
