How the formula works
Both petahenry and henry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in petahenrys by 1.000000e+15 to get henrys. To reverse the conversion, multiply a henry value by 1.000000e-15 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 Henry (H)?
The henry (H) is the SI unit of inductance, describing the voltage induced per unit rate of change of current.
How do I convert petahenrys to henrys?
Multiply the petahenry value by 1.000000e+15 to get the equivalent in henrys. For example, 5 PH × 1.000000e+15 = 5.000000e+15 H.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+15 is an exact, non-rounded value.
Can I convert henrys back to petahenrys?
Yes. Divide the henry value by 1.000000e+15, or multiply it by 1.000000e-15, to get petahenrys.
