Milliamps to Amps and Amps to Milliamps Calculator
Amps and milliamps describe the strength of a current, and their conversions are simple and straightforward - one just has to remember that "m" stands for "milli," which is, according to the SI prefixes table, 10-3 (one thousandth) of the main value.

How To Convert Milliamps to Amps?
The conversion from milliamps (mA) to amps (A) is simple.
There are 1000 milliamps in one amp. So to convert from milliamps to amps, you simply divide the number of milliamps by 1000.
Here's the formula:
Amps = Milliamps / 1000
For example, if you have 500 milliamps and you want to convert this to amps:
I (A) = 500 mA / 1000 = 0.5 A
So, 500 milliamps is equal to 0.5 amps.
How To Convert Amps To Milliamps?
The conversion from amps (A) to milliamps (mA) is also straightforward.
There are 1000 milliamps in one amp. So to convert from amps to milliamps, you simply multiply the number of amps by 1000.
Here's the formula:
Milliamps = Amps * 1000
For example, if you have 0.5 amps and you want to convert this to milliamps:
I(mA) = 0.5 A * 1000 = 500 mA
So, 0.5 amps is equal to 500 milliamps.
