How the formula works
Both gigahenry and attohenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in gigahenrys by 1.000000e+27 to get attohenrys. To reverse the conversion, multiply a attohenry value by 1.000000e-27 to get back to gigahenrys.
Frequently asked questions
What is Gigahenry (GH)?
A Gigahenry (GH) equals 1e+9 henry(s), a scaled unit of inductance used for giga-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 gigahenrys to attohenrys?
Multiply the gigahenry value by 1.000000e+27 to get the equivalent in attohenrys. For example, 5 GH × 1.000000e+27 = 5.000000e+27 aH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+27 is an exact, non-rounded value.
Can I convert attohenrys back to gigahenrys?
Yes. Divide the attohenry value by 1.000000e+27, or multiply it by 1.000000e-27, to get gigahenrys.
