Steps to Solve

Background Information

The ampere is symbolized as 'A' or 'amp' and is the fundamental unit of electrical current. When you see the prefix 'milli-' in front of another word or part of a word, you should remember that 'milli-' means one thousandth. You're probably very familiar with many 'milli-' terms already:

  • Millimeter
  • Milliliter
  • Millipede (although this term is erroneous since no known millipede actually has 1,000 legs)


Regardless, though, the prefix of 'milli-' works the same way for milliampere as it does for the terms you have already heard of. In other words, a milliampere, 'mA', is one thousandth of an ampere. You can alternatively view this as 1 ampere containing 1,000 milliamperes. Simply put:

1 A = 1,000 mA


1 mA = 1/1000 A
