How the formula works
Both terahenry and petahenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in terahenrys by 0.001 to get petahenrys. To reverse the conversion, multiply a petahenry value by 1000 to get back to terahenrys.
Frequently asked questions
What is Terahenry (TH)?
A Terahenry (TH) equals 1e+12 henry(s), a scaled unit of inductance used for tera-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 terahenrys to petahenrys?
Multiply the terahenry value by 0.001 to get the equivalent in petahenrys. For example, 5 TH × 0.001 = 0.005 PH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.001 is an exact, non-rounded value.
Can I convert petahenrys back to terahenrys?
Yes. Divide the petahenry value by 0.001, or multiply it by 1000, to get terahenrys.
