How the formula works
Both femtoampere and quectoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtoamperes by 1.000000e+15 to get quectoamperes. To reverse the conversion, multiply a quectoampere value by 1.000000e-15 to get back to femtoamperes.
Frequently asked questions
What is Femtoampere (fA)?
A Femtoampere (fA) equals 1e-15 ampere(s), a scaled unit of electric current used for femto-scale electrical work.
What is Quectoampere (qA)?
A Quectoampere (qA) equals 1e-30 ampere(s), a scaled unit of electric current used for quecto-scale electrical work.
How do I convert femtoamperes to quectoamperes?
Multiply the femtoampere value by 1.000000e+15 to get the equivalent in quectoamperes. For example, 5 fA × 1.000000e+15 = 5.000000e+15 qA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+15 is an exact, non-rounded value.
Can I convert quectoamperes back to femtoamperes?
Yes. Divide the quectoampere value by 1.000000e+15, or multiply it by 1.000000e-15, to get femtoamperes.
