How the formula works
Both millihenry and gigahenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in millihenrys by 1.000000e-12 to get gigahenrys. To reverse the conversion, multiply a gigahenry value by 1.000000e+12 to get back to millihenrys.
Frequently asked questions
What is Millihenry (mH)?
A Millihenry (mH) equals 1/1,000 henry(s), a scaled unit of inductance used for milli-scale electrical work.
What is Gigahenry (GH)?
A Gigahenry (GH) equals 1e+9 henry(s), a scaled unit of inductance used for giga-scale electrical work.
How do I convert millihenrys to gigahenrys?
Multiply the millihenry value by 1.000000e-12 to get the equivalent in gigahenrys. For example, 5 mH × 1.000000e-12 = 5.000000e-12 GH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-12 is an exact, non-rounded value.
Can I convert gigahenrys back to millihenrys?
Yes. Divide the gigahenry value by 1.000000e-12, or multiply it by 1.000000e+12, to get millihenrys.
