How the formula works
Both kilohenry and attohenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in kilohenrys by 1.000000e+21 to get attohenrys. To reverse the conversion, multiply a attohenry value by 1.000000e-21 to get back to kilohenrys.
Frequently asked questions
What is Kilohenry (kH)?
A Kilohenry (kH) equals 1,000 henry(s), a scaled unit of inductance used for kilo-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 kilohenrys to attohenrys?
Multiply the kilohenry value by 1.000000e+21 to get the equivalent in attohenrys. For example, 5 kH × 1.000000e+21 = 5.000000e+21 aH.
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 attohenrys back to kilohenrys?
Yes. Divide the attohenry value by 1.000000e+21, or multiply it by 1.000000e-21, to get kilohenrys.
