How the formula works
Both petaampere and ronnaampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in petaamperes by 1.000000e-12 to get ronnaamperes. To reverse the conversion, multiply a ronnaampere value by 1.000000e+12 to get back to petaamperes.
Frequently asked questions
What is Petaampere (PA)?
A Petaampere (PA) equals 1e+15 ampere(s), a scaled unit of electric current used for peta-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 petaamperes to ronnaamperes?
Multiply the petaampere value by 1.000000e-12 to get the equivalent in ronnaamperes. For example, 5 PA × 1.000000e-12 = 5.000000e-12 RA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-12 is an exact, non-rounded value.
Can I convert ronnaamperes back to petaamperes?
Yes. Divide the ronnaampere value by 1.000000e-12, or multiply it by 1.000000e+12, to get petaamperes.
