Microampere quick reference
| Microampere | Milliampere | Ampere | Kiloampere |
|---|---|---|---|
| 1 µA | = 0.001 mA | = 0.000001 A | = 1e-9 kA |
| 10 µA | = 0.01 mA | = 0.00001 A | = 1e-8 kA |
| 100 µA | = 0.1 mA | = 0.0001 A | = 1e-7 kA |
| 1000 µA | = 1 mA | = 0.001 A | = 0.000001 kA |
Where the microampere fits
The next smaller electric current unit is the nanoampere (nA). 1 µA = 1000 nA, and 1 nA = 0.001 µA.
The next larger electric current unit is the milliampere (mA). 1 µA = 0.001 mA, and 1 mA = 1000 µA.
