How the formula works
Both exaampere and rontoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in exaamperes by 1.000000e+45 to get rontoamperes. To reverse the conversion, multiply a rontoampere value by 1.000000e-45 to get back to exaamperes.
Frequently asked questions
What is Exaampere (EA)?
An Exaampere (EA) equals 1e+18 ampere(s), a scaled unit of electric current used for exa-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 exaamperes to rontoamperes?
Multiply the exaampere value by 1.000000e+45 to get the equivalent in rontoamperes. For example, 5 EA × 1.000000e+45 = 5.000000e+45 rA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+45 is an exact, non-rounded value.
Can I convert rontoamperes back to exaamperes?
Yes. Divide the rontoampere value by 1.000000e+45, or multiply it by 1.000000e-45, to get exaamperes.
