How the formula works
Both gigaampere and attoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in gigaamperes by 1.000000e+27 to get attoamperes. To reverse the conversion, multiply a attoampere value by 1.000000e-27 to get back to gigaamperes.
Frequently asked questions
What is Gigaampere (GA)?
A Gigaampere (GA) equals 1e+9 ampere(s), a scaled unit of electric current used for giga-scale electrical work.
What is Attoampere (aA)?
An Attoampere (aA) equals 1e-18 ampere(s), a scaled unit of electric current used for atto-scale electrical work.
How do I convert gigaamperes to attoamperes?
Multiply the gigaampere value by 1.000000e+27 to get the equivalent in attoamperes. For example, 5 GA × 1.000000e+27 = 5.000000e+27 aA.
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 attoamperes back to gigaamperes?
Yes. Divide the attoampere value by 1.000000e+27, or multiply it by 1.000000e-27, to get gigaamperes.
