How the formula works
Both attohenry and zeptohenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attohenrys by 1000 to get zeptohenrys. To reverse the conversion, multiply a zeptohenry value by 0.001 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 Zeptohenry (zH)?
A Zeptohenry (zH) equals 1e-21 henry(s), a scaled unit of inductance used for zepto-scale electrical work.
How do I convert attohenrys to zeptohenrys?
Multiply the attohenry value by 1000 to get the equivalent in zeptohenrys. For example, 5 aH × 1000 = 5000 zH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1000 is an exact, non-rounded value.
Can I convert zeptohenrys back to attohenrys?
Yes. Divide the zeptohenry value by 1000, or multiply it by 0.001, to get attohenrys.
