How the formula works
Both femtoampere and milliampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtoamperes by 1.000000e-12 to get milliamperes. To reverse the conversion, multiply a milliampere value by 1.000000e+12 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 Milliampere (mA)?
A Milliampere (mA) equals 1/1,000 ampere(s), a scaled unit of electric current used for milli-scale electrical work.
How do I convert femtoamperes to milliamperes?
Multiply the femtoampere value by 1.000000e-12 to get the equivalent in milliamperes. For example, 5 fA × 1.000000e-12 = 5.000000e-12 mA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-12 is an exact, non-rounded value.
Can I convert milliamperes back to femtoamperes?
Yes. Divide the milliampere value by 1.000000e-12, or multiply it by 1.000000e+12, to get femtoamperes.
