# How to convert amps to milliamps

How to convert electric current from amps (A) to milliamps (mA).

### amps to milliamps calculation formula

The current I in milliamps (mA) is equal to the current I_{ }in amps (A) times 1000
milliamps per amp:

*I*_{(mA)} = *I*_{(A)}* *×* *1000mA/A

So milliamps are equal to amps times 1000 milliamps per amp:

milliamp = amp × 1000

or

mA = A × 1000

#### Example

Convert current of 3 amps to milliamps:

The current I in milliamps (mA) is equal to 3 amps (A) times 1000mA/A:

*I*_{(mA)} = 3A × 1000mA/A = 3000mA
