How the formula works
Both petaampere and rontoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in petaamperes by 1.000000e+42 to get rontoamperes. To reverse the conversion, multiply a rontoampere value by 1.000000e-42 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 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 petaamperes to rontoamperes?
Multiply the petaampere value by 1.000000e+42 to get the equivalent in rontoamperes. For example, 5 PA × 1.000000e+42 = 5.000000e+42 rA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+42 is an exact, non-rounded value.
Can I convert rontoamperes back to petaamperes?
Yes. Divide the rontoampere value by 1.000000e+42, or multiply it by 1.000000e-42, to get petaamperes.
