nA
Rendered to 6 significant figures.
Formula
Formula
nA = mA × 1000000
Multiply any value in milliamperes by 1000000 to obtain the value in nanoamperes.
Worked example
Convert 1 mA to nA.
- 01Start with 1 mA.
- 02Multiply by the conversion factor: 1 × 1000000 = 1.00000e+6 nA.
Result1 mA = 1.00000e+6 nA

FAQ
What is the conversion factor from mA to nA?
1 mA equals 1000000 nA. To convert, multiply the value in milliamperes by 1000000.
How do I convert 1 mA to nA?
1 mA = 1.00000e+6 nA. For any value, multiply by 1000000.
How do I convert nA back to mA?
Divide by the same factor — or equivalently, multiply by 1e-6. So 1 nA = 1e-6 mA.
When would I need to convert milliampere to nanoampere?
Current conversions between mA 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).
