How the formula works
Both kiloampere and femtoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in kiloamperes by 1.000000e+18 to get femtoamperes. To reverse the conversion, multiply a femtoampere value by 1.000000e-18 to get back to kiloamperes.
Frequently asked questions
What is Kiloampere (kA)?
A Kiloampere (kA) equals 1,000 ampere(s), a scaled unit of electric current used for kilo-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 kiloamperes to femtoamperes?
Multiply the kiloampere value by 1.000000e+18 to get the equivalent in femtoamperes. For example, 5 kA × 1.000000e+18 = 5.000000e+18 fA.
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 femtoamperes back to kiloamperes?
Yes. Divide the femtoampere value by 1.000000e+18, or multiply it by 1.000000e-18, to get kiloamperes.
