How the formula works
Both attohenry and hectohenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attohenrys by 1.000000e-20 to get hectohenrys. To reverse the conversion, multiply a hectohenry value by 1.000000e+20 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 Hectohenry (hH)?
A Hectohenry (hH) equals 100 henry(s), a scaled unit of inductance used for hecto-scale electrical work.
How do I convert attohenrys to hectohenrys?
Multiply the attohenry value by 1.000000e-20 to get the equivalent in hectohenrys. For example, 5 aH × 1.000000e-20 = 5.000000e-20 hH.
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 hectohenrys back to attohenrys?
Yes. Divide the hectohenry value by 1.000000e-20, or multiply it by 1.000000e+20, to get attohenrys.
