The ampere (symbol: A) is the SI unit of electric current. The ampere, in practice often shortened to amp, is an SI base unit, and is named after André-Marie Ampère, one of the main discoverers of electromagnetism.
In practical terms, the ampere is a measure of the amount of electric charge passing a point per unit time. Around 6.242 × 1018 electrons passing a given point each second constitutes one ampere. (Since electrons have negative charge, they flow in the opposite direction to the conventional current.)
Electric current is the flow of electric charge. The electric charge may be either electrons or ions. - Wikipedia
The table below gives conversion factors to move back and forth between units of electric current.
Standard unit = Ampere (A)
|1 abA =||1||10||2.998 * 1010|
|1 A =||0.1||1||2.998 * 109|
|1 statA =||3.336 * 10-11||3.336 * 10-10||1|
Note: The prefix "ab" is used to indicate an electromagnetic unit in the centimeter-gram-second
The prefix "stat" is used to indicate an electrical unit in the electrostatic centimeter-gram-second system of units.
