Etymology
The word ampere-minute comes from joining the unit ampere, named after the French scientist Ampère and meaning electric 'current', with minute, a common word for a unit of 'time'. So an ampere-minute measures how much electric charge flows when a current of one ampere runs for one minute, which equals 60 coulombs.
