How the formula works
Both rontoampere and microampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in rontoamperes by 1.000000e-21 to get microamperes. To reverse the conversion, multiply a microampere value by 1.000000e+21 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 Microampere (uA)?
A Microampere (uA) equals 1e-06 ampere(s), a scaled unit of electric current used for micro-scale electrical work.
How do I convert rontoamperes to microamperes?
Multiply the rontoampere value by 1.000000e-21 to get the equivalent in microamperes. For example, 5 rA × 1.000000e-21 = 5.000000e-21 uA.
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 microamperes back to rontoamperes?
Yes. Divide the microampere value by 1.000000e-21, or multiply it by 1.000000e+21, to get rontoamperes.
