What is a milliampere equivalent to in amperes?

A milliampere is a unit of electric current that represents one-thousandth of an ampere. This relationship can be expressed mathematically as:

1 milliampere = 0.001 ampere

This means that if you have a current measurement in milliamperes, you can convert it to amperes by dividing by 1,000. Therefore, the correct answer explains the direct conversion between these two units of measurement in electrical engineering. Understanding this conversion is vital for tasks involving current analysis, circuitry, and troubleshooting in electrical systems, which are common tasks for a transit electrical helper.
