Formula
Formula
nA = A × 1e+9
Multiply any value in amperes by 1e+9 to obtain the value in nanoamperes.
Worked example
Convert 1 A to nA.
- 01Start with 1 A.
- 02Multiply by the conversion factor: 1 × 1e+9 = 1e+9 nA.
Result1 A = 1e+9 nA

FAQ
What is the conversion factor from A to nA?
1 A equals 1e+9 nA. To convert, multiply the value in amperes by 1e+9.
How do I convert 1 A to nA?
1 A = 1e+9 nA. For any value, multiply by 1e+9.
How do I convert nA back to A?
Divide by the same factor — or equivalently, multiply by 1e-9. So 1 nA = 1e-9 A.
When would I need to convert ampere to nanoampere?
Current conversions between A and nA appear in motor and cable sizing, instrumentation loop design (4–20 mA), battery characterisation and electronics. Amperes are standard for power circuits; milliamperes and microamperes are the working units for signal conditioning and sensor outputs.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
