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
