How the formula works
Both yoctoampere and femtoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in yoctoamperes by 1.000000e-09 to get femtoamperes. To reverse the conversion, multiply a femtoampere value by 1.000000e+09 to get back to yoctoamperes.
Frequently asked questions
What is Yoctoampere (yA)?
A Yoctoampere (yA) equals 1e-24 ampere(s), a scaled unit of electric current used for yocto-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 yoctoamperes to femtoamperes?
Multiply the yoctoampere value by 1.000000e-09 to get the equivalent in femtoamperes. For example, 5 yA × 1.000000e-09 = 5.000000e-09 fA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-09 is an exact, non-rounded value.
Can I convert femtoamperes back to yoctoamperes?
Yes. Divide the femtoampere value by 1.000000e-09, or multiply it by 1.000000e+09, to get yoctoamperes.
