How the formula works
Both femtoampere and kiloampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtoamperes by 1.000000e-18 to get kiloamperes. To reverse the conversion, multiply a kiloampere value by 1.000000e+18 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 Kiloampere (kA)?
A Kiloampere (kA) equals 1,000 ampere(s), a scaled unit of electric current used for kilo-scale electrical work.
How do I convert femtoamperes to kiloamperes?
Multiply the femtoampere value by 1.000000e-18 to get the equivalent in kiloamperes. For example, 5 fA × 1.000000e-18 = 5.000000e-18 kA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-18 is an exact, non-rounded value.
Can I convert kiloamperes back to femtoamperes?
Yes. Divide the kiloampere value by 1.000000e-18, or multiply it by 1.000000e+18, to get femtoamperes.
