How many milli amps in 1 ampere? The answer is 1000. We assume you are converting between milliampere and ampere. You can view more details on each measurement unit: milli amps or ampere The SI base unit for electric current is the ampere. 1 ampere is equal to 1000 milli amps, or 1 ampere. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between milliamperes and amperes. Type in your own numbers in the form to convert the units!
1 milli amps to ampere = 0.001 ampere
10 milli amps to ampere = 0.01 ampere
50 milli amps to ampere = 0.05 ampere
100 milli amps to ampere = 0.1 ampere
200 milli amps to ampere = 0.2 ampere
500 milli amps to ampere = 0.5 ampere
1000 milli amps to ampere = 1 ampere
You can do the reverse unit conversion from ampere to milli amps, or enter any two units below:
The SI prefix "milli" represents a factor of 10-3, or in exponential notation, 1E-3.
So 1 milliampere = 10-3 ampere.
In physics, the ampere (symbol: A, often informally abbreviated to amp) is the SI base unit used to measure electrical currents. The present definition, adopted by the 9th CGPM in 1948 is: "one ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed one metre apart in vacuum, would produce between these conductors a force equal to 2 × 10-7 newton per metre of length".
