How to Convert Ampere to Nanoampere

To convert from Ampere (A) to Nanoampere (nA), multiply the value by 1,000,000,000.

Formula: nA = A × 1.000000e+9

Reverse: A = nA × 1.000000e-9

Step-by-Step Example

Start with your value in Ampere. For example: 5 A
Multiply by the conversion factor: 5 x 1,000,000,000
The result is: 5,000,000,000 nA

About Ampere

The ampere (A) is a unit of electric current. One ampere equals 1 ampere. UnitConvertLab converts it against every other electric current unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: electric current calculations, engineering and science, education.

About Nanoampere

The nanoampere (nA) is a unit of electric current. One nanoampere equals 1.000000 × 10^-9 amperes. UnitConvertLab converts it against every other electric current unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: electric current calculations, engineering and science, education.
