1. Convert to base units
amperes = input value x input unit factor
Every supported current unit is stored as a factor relative to amperes.

Common conversions
Useful current conversion factors
| Conversion | Factor | Typical use |
|---|---|---|
| Amps to milliamps | mA = A x 1000 | Circuit loads and electronics |
| Milliamps to amps | A = mA / 1000 | Power supply and device current |
| Microamps to milliamps | mA = uA / 1000 | Sensors and low-power circuits |
| Nanoamps to amps | A = nA x 1e-9 | Leakage current and instrumentation |
| Kiloamps to amps | A = kA x 1000 | Fault current and power systems |
| Megaamps to amps | A = MA x 1,000,000 | Large-scale power and physics examples |
How it works
Current conversion method
2. Convert to target units
target value = base value / target unit factor
The selected result and table values are calculated from the same base value.
3. Check precision
rounding depends on scale
Very small and very large values use compact scientific notation to stay readable.
