How the formula works
Both centiampere and ronnaampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in centiamperes by 1.000000e-29 to get ronnaamperes. To reverse the conversion, multiply a ronnaampere value by 1.000000e+29 to get back to centiamperes.
Frequently asked questions
What is Centiampere (cA)?
A Centiampere (cA) equals 1/100 ampere(s), a scaled unit of electric current used for centi-scale electrical work.
What is Ronnaampere (RA)?
A Ronnaampere (RA) equals 1e+27 ampere(s), a scaled unit of electric current used for ronna-scale electrical work.
How do I convert centiamperes to ronnaamperes?
Multiply the centiampere value by 1.000000e-29 to get the equivalent in ronnaamperes. For example, 5 cA × 1.000000e-29 = 5.000000e-29 RA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-29 is an exact, non-rounded value.
Can I convert ronnaamperes back to centiamperes?
Yes. Divide the ronnaampere value by 1.000000e-29, or multiply it by 1.000000e+29, to get centiamperes.
