How the formula works
Both femtoampere and zeptoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtoamperes by 1.000000e+06 to get zeptoamperes. To reverse the conversion, multiply a zeptoampere value by 0.000001 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 Zeptoampere (zA)?
A Zeptoampere (zA) equals 1e-21 ampere(s), a scaled unit of electric current used for zepto-scale electrical work.
How do I convert femtoamperes to zeptoamperes?
Multiply the femtoampere value by 1.000000e+06 to get the equivalent in zeptoamperes. For example, 5 fA × 1.000000e+06 = 5.000000e+06 zA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+06 is an exact, non-rounded value.
Can I convert zeptoamperes back to femtoamperes?
Yes. Divide the zeptoampere value by 1.000000e+06, or multiply it by 0.000001, to get femtoamperes.
