How many amp in 1 milli-amps? The answer is 0.001. We assume you are converting between ampere and milliampere. You can view more details on each measurement unit: amp or milli-amps The SI base unit for electric current is the ampere. 1 ampere is equal to 1 amp, or 1000 milli-amps. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between amperes and milliamperes. Type in your own numbers in the form to convert the units!
1 amp to milli-amps = 1000 milli-amps
2 amp to milli-amps = 2000 milli-amps
3 amp to milli-amps = 3000 milli-amps
4 amp to milli-amps = 4000 milli-amps
5 amp to milli-amps = 5000 milli-amps
6 amp to milli-amps = 6000 milli-amps
7 amp to milli-amps = 7000 milli-amps
8 amp to milli-amps = 8000 milli-amps
9 amp to milli-amps = 9000 milli-amps
10 amp to milli-amps = 10000 milli-amps
You can do the reverse unit conversion from milli-amps to amp, or enter any two units below:
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".
The SI prefix "milli" represents a factor of 10-3, or in exponential notation, 1E-3.
So 1 milliampere = 10-3 ampere.
