How the formula works
Both rontoampere and femtoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in rontoamperes by 1.000000e-12 to get femtoamperes. To reverse the conversion, multiply a femtoampere value by 1.000000e+12 to get back to rontoamperes.
Frequently asked questions
What is Rontoampere (rA)?
A Rontoampere (rA) equals 1e-27 ampere(s), a scaled unit of electric current used for ronto-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 rontoamperes to femtoamperes?
Multiply the rontoampere value by 1.000000e-12 to get the equivalent in femtoamperes. For example, 5 rA × 1.000000e-12 = 5.000000e-12 fA.
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 femtoamperes back to rontoamperes?
Yes. Divide the femtoampere value by 1.000000e-12, or multiply it by 1.000000e+12, to get rontoamperes.
