How the formula works
Both hectohenry and attohenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in hectohenrys by 1.000000e+20 to get attohenrys. To reverse the conversion, multiply a attohenry value by 1.000000e-20 to get back to hectohenrys.
Frequently asked questions
What is Hectohenry (hH)?
A Hectohenry (hH) equals 100 henry(s), a scaled unit of inductance used for hecto-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 hectohenrys to attohenrys?
Multiply the hectohenry value by 1.000000e+20 to get the equivalent in attohenrys. For example, 5 hH × 1.000000e+20 = 5.000000e+20 aH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+20 is an exact, non-rounded value.
Can I convert attohenrys back to hectohenrys?
Yes. Divide the attohenry value by 1.000000e+20, or multiply it by 1.000000e-20, to get hectohenrys.
