How the formula works
Both nanoampere and rontoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in nanoamperes by 1.000000e+18 to get rontoamperes. To reverse the conversion, multiply a rontoampere value by 1.000000e-18 to get back to nanoamperes.
Frequently asked questions
What is Nanoampere (nA)?
A Nanoampere (nA) equals 1e-09 ampere(s), a scaled unit of electric current used for nano-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 nanoamperes to rontoamperes?
Multiply the nanoampere value by 1.000000e+18 to get the equivalent in rontoamperes. For example, 5 nA × 1.000000e+18 = 5.000000e+18 rA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+18 is an exact, non-rounded value.
Can I convert rontoamperes back to nanoamperes?
Yes. Divide the rontoampere value by 1.000000e+18, or multiply it by 1.000000e-18, to get nanoamperes.
