How the formula works
Both terahenry and femtohenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in terahenrys by 1.000000e+27 to get femtohenrys. To reverse the conversion, multiply a femtohenry value by 1.000000e-27 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 Femtohenry (fH)?
A Femtohenry (fH) equals 1e-15 henry(s), a scaled unit of inductance used for femto-scale electrical work.
How do I convert terahenrys to femtohenrys?
Multiply the terahenry value by 1.000000e+27 to get the equivalent in femtohenrys. For example, 5 TH × 1.000000e+27 = 5.000000e+27 fH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+27 is an exact, non-rounded value.
Can I convert femtohenrys back to terahenrys?
Yes. Divide the femtohenry value by 1.000000e+27, or multiply it by 1.000000e-27, to get terahenrys.
