How the formula works
Both yoctohenry and millihenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in yoctohenrys by 1.000000e-21 to get millihenrys. To reverse the conversion, multiply a millihenry value by 1.000000e+21 to get back to yoctohenrys.
Frequently asked questions
What is Yoctohenry (yH)?
A Yoctohenry (yH) equals 1e-24 henry(s), a scaled unit of inductance used for yocto-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 yoctohenrys to millihenrys?
Multiply the yoctohenry value by 1.000000e-21 to get the equivalent in millihenrys. For example, 5 yH × 1.000000e-21 = 5.000000e-21 mH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-21 is an exact, non-rounded value.
Can I convert millihenrys back to yoctohenrys?
Yes. Divide the millihenry value by 1.000000e-21, or multiply it by 1.000000e+21, to get yoctohenrys.
