About these units
The ampere (A) is an SI base or derived unit of electric current.
The milliampere (mA) is a metric unit of electric current, equal to 0.001 amperes.
Going the other way, 1 milliampere = 0.001 amperes. Current is measured in amperes, but datasheets and lab work range from nanoamps in sensors to kiloamps in industrial supplies.
