How the formula works
Both zeptoampere and femtoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in zeptoamperes by 1.000000e-06 to get femtoamperes. To reverse the conversion, multiply a femtoampere value by 1.000000e+06 to get back to zeptoamperes.
Frequently asked questions
What is Zeptoampere (zA)?
A Zeptoampere (zA) equals 1e-21 ampere(s), a scaled unit of electric current used for zepto-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 zeptoamperes to femtoamperes?
Multiply the zeptoampere value by 1.000000e-06 to get the equivalent in femtoamperes. For example, 5 zA × 1.000000e-06 = 0.000005 fA.
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 femtoamperes back to zeptoamperes?
Yes. Divide the femtoampere value by 1.000000e-06, or multiply it by 1.000000e+06, to get zeptoamperes.
