Electric current converter
Amps, and the smaller units meters read in. 5 units, converted from one table of exact factors.
—
1 ampere in every other electric current unit
Computed by the same engine that runs the converter above, so these can never drift apart from it.
| From | Equals | Unit |
|---|---|---|
| 1 ampere | 1,000 | milliampere (mA) |
| 1 ampere | 1,000,000 | microampere (µA) |
| 1 ampere | 0.001 | kiloampere (kA) |
| 1 ampere | 0.1 | abampere (abA) |
What each unit actually is
Most converters give you a number and stop. Where a figure is exact by definition we say so, and where it is an average or shifts with conditions we say that too — that is usually the thing you needed to know.
| Unit | Symbol | What it actually is |
|---|---|---|
| ampere | A | SI base unit. Defined from the elementary charge since 2019. |
| milliampere | mA | |
| microampere | µA | |
| kiloampere | kA | |
| abampere | abA | The CGS unit. Ten amperes. |
