How the formula works
Both terahenry and millihenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in terahenrys by 1.000000e+15 to get millihenrys. To reverse the conversion, multiply a millihenry value by 1.000000e-15 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 Millihenry (mH)?
A Millihenry (mH) equals 1/1,000 henry(s), a scaled unit of inductance used for milli-scale electrical work.
How do I convert terahenrys to millihenrys?
Multiply the terahenry value by 1.000000e+15 to get the equivalent in millihenrys. For example, 5 TH × 1.000000e+15 = 5.000000e+15 mH.
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 millihenrys back to terahenrys?
Yes. Divide the millihenry value by 1.000000e+15, or multiply it by 1.000000e-15, to get terahenrys.
