Current Converter - Convert Between Ampere, mA, kA Online Free
Convert between amperes, milliamperes, microamperes, and kiloamperes.
What Is a Current Converter?
A current converter converts between different electric current units.
Supported Units
- Ampere (A) — SI base unit. 1 A = 1 C/s.
- Milliampere (mA) — 1/1000 A. Electronics.
- Microampere (uA) — 1/1,000,000 A. Precision instruments.
- Kiloampere (kA) — 1000 A. Industrial power.
How Does Current Converter Work?
1 A = 1000 mA = 1,000,000 uA. 1 kA = 1000 A.
How to Use This Tool
- Enter a numeric value — Type the measurement you want to convert.
