How the formula works
Both megaampere and rontoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in megaamperes by 1.000000e+33 to get rontoamperes. To reverse the conversion, multiply a rontoampere value by 1.000000e-33 to get back to megaamperes.
Frequently asked questions
What is Megaampere (MA)?
A Megaampere (MA) equals 1e+6 ampere(s), a scaled unit of electric current used for mega-scale electrical work.
What is Rontoampere (rA)?
A Rontoampere (rA) equals 1e-27 ampere(s), a scaled unit of electric current used for ronto-scale electrical work.
How do I convert megaamperes to rontoamperes?
Multiply the megaampere value by 1.000000e+33 to get the equivalent in rontoamperes. For example, 5 MA × 1.000000e+33 = 5.000000e+33 rA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+33 is an exact, non-rounded value.
Can I convert rontoamperes back to megaamperes?
Yes. Divide the rontoampere value by 1.000000e+33, or multiply it by 1.000000e-33, to get megaamperes.
