How the formula works
Both rontohenry and petahenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in rontohenrys by 1.000000e-42 to get petahenrys. To reverse the conversion, multiply a petahenry value by 1.000000e+42 to get back to rontohenrys.
Frequently asked questions
What is Rontohenry (rH)?
A Rontohenry (rH) equals 1e-27 henry(s), a scaled unit of inductance used for ronto-scale electrical work.
What is Petahenry (PH)?
A Petahenry (PH) equals 1e+15 henry(s), a scaled unit of inductance used for peta-scale electrical work.
How do I convert rontohenrys to petahenrys?
Multiply the rontohenry value by 1.000000e-42 to get the equivalent in petahenrys. For example, 5 rH × 1.000000e-42 = 5.000000e-42 PH.
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 petahenrys back to rontohenrys?
Yes. Divide the petahenry value by 1.000000e-42, or multiply it by 1.000000e+42, to get rontohenrys.
