**According to ConvertUnits.com, there are 1000 milliamps or "milliamperes" in 1 volt/watt.** The ampere is the SI base unit for electric current. One ampere is also equal to 1000 milliamperes or 1 volt/watt. The term "milliampere" is abbreviated "mA" according to Reference.com and originated in the late 19th century.

With amps calculations, the current in amps is equal to the voltage divided by resistance in ohms. When calculating amps, a person can also use the formula current in amps is equal to power in watts divided by voltage in volts. Furthermore, the current in amps is also equal to the square root of the watts divided by resistance in ohms.
