Convert amperes to milliamperes for electrical calculations
Formula: milliamperes = amperes × 1,000
Note: 1 ampere = 1,000 milliamperes
The ampere is the SI base unit of electric current.
The milliampere is a smaller unit for measuring electric current.
| Amperes | Milliamperes | Application |
|---|---|---|
| 0.001 A | 1 mA | Small LED |
| 0.02 A | 20 mA | Standard LED |
| 0.1 A | 100 mA | Electronic circuit |
| 1 A | 1,000 mA | Small motor |
Milliamperes = Amperes × 1,000
Amperes = Milliamperes ÷ 1,000
