What is one milliampere equivalent to?

One milliampere is equivalent to one thousandth of an ampere. In the metric system, the prefix "milli" denotes a factor of one-thousandth (1/1000). Therefore, when you convert milliamperes to amperes, you divide the number of milliamperes by 1000. For instance, if you have 1 milliampere (mA), you can express it mathematically as:

1 mA = 1/1000 A = 0.001 A

Understanding this conversion is crucial, especially in fields related to electrical measurements. It helps in interpreting measurements accurately, ensuring that treatments using electrical devices in beauty therapy, such as galvanic and faradic currents, are safe and effective.
