How the formula works
Both attohenry and ronnahenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attohenrys by 1.000000e-45 to get ronnahenrys. To reverse the conversion, multiply a ronnahenry value by 1.000000e+45 to get back to attohenrys.
Frequently asked questions
What is Attohenry (aH)?
An Attohenry (aH) equals 1e-18 henry(s), a scaled unit of inductance used for atto-scale electrical work.
What is Ronnahenry (RH)?
A Ronnahenry (RH) equals 1e+27 henry(s), a scaled unit of inductance used for ronna-scale electrical work.
How do I convert attohenrys to ronnahenrys?
Multiply the attohenry value by 1.000000e-45 to get the equivalent in ronnahenrys. For example, 5 aH × 1.000000e-45 = 5.000000e-45 RH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-45 is an exact, non-rounded value.
Can I convert ronnahenrys back to attohenrys?
Yes. Divide the ronnahenry value by 1.000000e-45, or multiply it by 1.000000e+45, to get attohenrys.
