How the formula works
Both rontoampere and centiampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in rontoamperes by 1.000000e-25 to get centiamperes. To reverse the conversion, multiply a centiampere value by 1.000000e+25 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 Centiampere (cA)?
A Centiampere (cA) equals 1/100 ampere(s), a scaled unit of electric current used for centi-scale electrical work.
How do I convert rontoamperes to centiamperes?
Multiply the rontoampere value by 1.000000e-25 to get the equivalent in centiamperes. For example, 5 rA × 1.000000e-25 = 5.000000e-25 cA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-25 is an exact, non-rounded value.
Can I convert centiamperes back to rontoamperes?
Yes. Divide the centiampere value by 1.000000e-25, or multiply it by 1.000000e+25, to get rontoamperes.
