Frequently asked questions about electric current
How many milliamperes are in 1 ampere?+
1 ampere equals 1,000 milliamperes.
What is the difference between AC and DC current?+
Direct current flows in one direction. Alternating current periodically reverses direction, as used in household electricity.
Which current units does this converter support?+
It supports SI current units from nanoamperes to megaamperes, plus historical CGS units.
