How the formula works
Both petahenry and attohenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in petahenrys by 1.000000e+33 to get attohenrys. To reverse the conversion, multiply a attohenry value by 1.000000e-33 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 Attohenry (aH)?
An Attohenry (aH) equals 1e-18 henry(s), a scaled unit of inductance used for atto-scale electrical work.
How do I convert petahenrys to attohenrys?
Multiply the petahenry value by 1.000000e+33 to get the equivalent in attohenrys. For example, 5 PH × 1.000000e+33 = 5.000000e+33 aH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+33 is an exact, non-rounded value.
Can I convert attohenrys back to petahenrys?
Yes. Divide the attohenry value by 1.000000e+33, or multiply it by 1.000000e-33, to get petahenrys.
