Current Converter
Convert electric current between amperes, milliamperes and kiloamperes.

Quick answer
Electric current is the rate of charge flow, measured in amperes: one coulomb per second. One milliampere is 0.001 A and one kiloampere is 1,000 A. The abampere, an older CGS unit, is exactly 10 amperes. Household circuits are typically rated between 10 and 20 amperes.
| Ampere (A) | 1 |
| Milliampere (mA) | 1000 |
| Microampere (µA) | 1000000 |
| Kiloampere (kA) | 0.001 |
| Abampere (abA) | 0.1 |
| Biot (Bi) | 0.1 |
About the Current Converter
Electric current is the rate of flow of electric charge. The SI unit is the ampere, with milliamperes and kiloamperes used for smaller and larger currents.
This converter helps when comparing current ratings across devices and circuits.
