How the formula works
Both megahenry and millihenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in megahenrys by 1.000000e+09 to get millihenrys. To reverse the conversion, multiply a millihenry value by 1.000000e-09 to get back to megahenrys.
Frequently asked questions
What is Megahenry (MH)?
A Megahenry (MH) equals 1e+6 henry(s), a scaled unit of inductance used for mega-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 megahenrys to millihenrys?
Multiply the megahenry value by 1.000000e+09 to get the equivalent in millihenrys. For example, 5 MH × 1.000000e+09 = 5.000000e+09 mH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+09 is an exact, non-rounded value.
Can I convert millihenrys back to megahenrys?
Yes. Divide the millihenry value by 1.000000e+09, or multiply it by 1.000000e-09, to get megahenrys.
