How the formula works
Both gigaampere and femtoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in gigaamperes by 1.000000e+24 to get femtoamperes. To reverse the conversion, multiply a femtoampere value by 1.000000e-24 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 Femtoampere (fA)?
A Femtoampere (fA) equals 1e-15 ampere(s), a scaled unit of electric current used for femto-scale electrical work.
How do I convert gigaamperes to femtoamperes?
Multiply the gigaampere value by 1.000000e+24 to get the equivalent in femtoamperes. For example, 5 GA × 1.000000e+24 = 5.000000e+24 fA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+24 is an exact, non-rounded value.
Can I convert femtoamperes back to gigaamperes?
Yes. Divide the femtoampere value by 1.000000e+24, or multiply it by 1.000000e-24, to get gigaamperes.
