How the formula works
Both petahenry and decahenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in petahenrys by 1.000000e+14 to get decahenrys. To reverse the conversion, multiply a decahenry value by 1.000000e-14 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 Decahenry (daH)?
A Decahenry (daH) equals 10 henry(s), a scaled unit of inductance used for deca-scale electrical work.
How do I convert petahenrys to decahenrys?
Multiply the petahenry value by 1.000000e+14 to get the equivalent in decahenrys. For example, 5 PH × 1.000000e+14 = 5.000000e+14 daH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+14 is an exact, non-rounded value.
Can I convert decahenrys back to petahenrys?
Yes. Divide the decahenry value by 1.000000e+14, or multiply it by 1.000000e-14, to get petahenrys.
