How the formula works
Both yoctohenry and petahenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in yoctohenrys by 1.000000e-39 to get petahenrys. To reverse the conversion, multiply a petahenry value by 1.000000e+39 to get back to yoctohenrys.
Frequently asked questions
What is Yoctohenry (yH)?
A Yoctohenry (yH) equals 1e-24 henry(s), a scaled unit of inductance used for yocto-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 yoctohenrys to petahenrys?
Multiply the yoctohenry value by 1.000000e-39 to get the equivalent in petahenrys. For example, 5 yH × 1.000000e-39 = 5.000000e-39 PH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-39 is an exact, non-rounded value.
Can I convert petahenrys back to yoctohenrys?
Yes. Divide the petahenry value by 1.000000e-39, or multiply it by 1.000000e+39, to get yoctohenrys.
