How the formula works
Both femtoampere and megaampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtoamperes by 1.000000e-21 to get megaamperes. To reverse the conversion, multiply a megaampere value by 1.000000e+21 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 Megaampere (MA)?
A Megaampere (MA) equals 1e+6 ampere(s), a scaled unit of electric current used for mega-scale electrical work.
How do I convert femtoamperes to megaamperes?
Multiply the femtoampere value by 1.000000e-21 to get the equivalent in megaamperes. For example, 5 fA × 1.000000e-21 = 5.000000e-21 MA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-21 is an exact, non-rounded value.
Can I convert megaamperes back to femtoamperes?
Yes. Divide the megaampere value by 1.000000e-21, or multiply it by 1.000000e+21, to get femtoamperes.
