How the formula works
Both gigaohm and attoohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in gigaohms by 1.000000e+27 to get attoohms. To reverse the conversion, multiply a attoohm value by 1.000000e-27 to get back to gigaohms.
Frequently asked questions
What is Gigaohm (GΩ)?
A Gigaohm (GΩ) equals 1e+9 ohm(s), a scaled unit of electrical resistance used for giga-scale electrical work.
What is Attoohm (aΩ)?
An Attoohm (aΩ) equals 1e-18 ohm(s), a scaled unit of electrical resistance used for atto-scale electrical work.
How do I convert gigaohms to attoohms?
Multiply the gigaohm value by 1.000000e+27 to get the equivalent in attoohms. For example, 5 GΩ × 1.000000e+27 = 5.000000e+27 aΩ.
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 attoohms back to gigaohms?
Yes. Divide the attoohm value by 1.000000e+27, or multiply it by 1.000000e-27, to get gigaohms.
