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