How the formula works
Both ronnaampere and milliampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in ronnaamperes by 1.000000e+30 to get milliamperes. To reverse the conversion, multiply a milliampere value by 1.000000e-30 to get back to ronnaamperes.
Frequently asked questions
What is Ronnaampere (RA)?
A Ronnaampere (RA) equals 1e+27 ampere(s), a scaled unit of electric current used for ronna-scale electrical work.
What is Milliampere (mA)?
A Milliampere (mA) equals 1/1,000 ampere(s), a scaled unit of electric current used for milli-scale electrical work.
How do I convert ronnaamperes to milliamperes?
Multiply the ronnaampere value by 1.000000e+30 to get the equivalent in milliamperes. For example, 5 RA × 1.000000e+30 = 5.000000e+30 mA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+30 is an exact, non-rounded value.
Can I convert milliamperes back to ronnaamperes?
Yes. Divide the milliampere value by 1.000000e+30, or multiply it by 1.000000e-30, to get ronnaamperes.
