How the formula works
Both yottahenry and attohenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in yottahenrys by 1.000000e+42 to get attohenrys. To reverse the conversion, multiply a attohenry value by 1.000000e-42 to get back to yottahenrys.
Frequently asked questions
What is Yottahenry (YH)?
A Yottahenry (YH) equals 1e+24 henry(s), a scaled unit of inductance used for yotta-scale electrical work.
What is Attohenry (aH)?
An Attohenry (aH) equals 1e-18 henry(s), a scaled unit of inductance used for atto-scale electrical work.
How do I convert yottahenrys to attohenrys?
Multiply the yottahenry value by 1.000000e+42 to get the equivalent in attohenrys. For example, 5 YH × 1.000000e+42 = 5.000000e+42 aH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+42 is an exact, non-rounded value.
Can I convert attohenrys back to yottahenrys?
Yes. Divide the attohenry value by 1.000000e+42, or multiply it by 1.000000e-42, to get yottahenrys.
