How the formula works
Both deciampere and ronnaampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in deciamperes by 1.000000e-28 to get ronnaamperes. To reverse the conversion, multiply a ronnaampere value by 1.000000e+28 to get back to deciamperes.
Frequently asked questions
What is Deciampere (dA)?
A Deciampere (dA) equals 1/10 ampere(s), a scaled unit of electric current used for deci-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 deciamperes to ronnaamperes?
Multiply the deciampere value by 1.000000e-28 to get the equivalent in ronnaamperes. For example, 5 dA × 1.000000e-28 = 5.000000e-28 RA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-28 is an exact, non-rounded value.
Can I convert ronnaamperes back to deciamperes?
Yes. Divide the ronnaampere value by 1.000000e-28, or multiply it by 1.000000e+28, to get deciamperes.
