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