Etymology
Milliampere is made of the prefix milli- meaning 'one thousandth', as in millimeter or milligram, and ampere, named after the scientist Ampère and used as the 'unit of electric current'. So a milliampere is one thousandth of an ampere, which is why we use it for very small electric currents.
