Which is equal to 3000 milliamperes?

The prefix 'milli' means one one-thousandth of a base unit. Because of this relationship, there are exactly 1000 milliamperes in a single ampere. To convert from milliamperes (mA) to base amperes (A), you must divide the given number by 1000. Taking 3000 and dividing it by 1000 gives you exactly 3. Moving the decimal point three spaces to the left achieves the same result, confirming that 3000 milliamperes is 3 amperes. Distractor answers often test whether you know which direction to move the decimal point. Multiplying by 1000 results in the incorrect 3,000,000, while dividing by 10,000 yields 0.3.
