How the formula works
Both femtoampere and attoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtoamperes by 1000 to get attoamperes. To reverse the conversion, multiply a attoampere value by 0.001 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 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 femtoamperes to attoamperes?
Multiply the femtoampere value by 1000 to get the equivalent in attoamperes. For example, 5 fA × 1000 = 5000 aA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1000 is an exact, non-rounded value.
Can I convert attoamperes back to femtoamperes?
Yes. Divide the attoampere value by 1000, or multiply it by 0.001, to get femtoamperes.
