Nanoampere quick reference
| Nanoampere | Ampere | Milliampere | Kiloampere |
|---|---|---|---|
| 1 nA | = 1e-9 A | = 0.000001 mA | = 1e-12 kA |
| 10 nA | = 1e-8 A | = 0.00001 mA | = 1e-11 kA |
| 100 nA | = 1e-7 A | = 0.0001 mA | = 1e-10 kA |
| 1000 nA | = 0.000001 A | = 0.001 mA | = 1e-9 kA |
Where the nanoampere fits
The next smaller electric current unit is the statampere (statA). 1 nA = 2.99792458 statA, and 1 statA ≈ 0.3335640952 nA.
The next larger electric current unit is the microampere (µA). 1 nA = 0.001 µA, and 1 µA = 1000 nA.
