Amperes: conversions & definition
Amperes (A) represent electric current. One unit equals 10^0 A. Electric current is the rate of electric charge flow. One ampere is one coulomb per second.

Keep the quantity consistent
Choose units that represent the same quantity and preserve the measurement conditions. A scale conversion changes the number and unit together; it does not change the physical amount or improve the accuracy of your measurement.
