How to convert Milliamperes to Amperes

To transform a milliampere measurement to an ampere measurement, division the electric present by the conversion ratio.

due to the fact that one ampere is equal to 1,000 milliamperes, you have the right to use this simple formula to convert:


Milliamperes and amperes room both units supplied to measure electric current. Keep analysis to learn an ext about every unit the measure.

One milliampere is same to 1/1,000 of one ampere, i m sorry is the electrical current equal come the flow of one coulomb per second.

The milliampere is a many of the ampere, which is the SI base unit for electric current. In the metric system, "milli" is the prefix because that 10-3. A milliampere is sometimes additionally referred to together a milliamp. Milliamperes have the right to be abbreviated as mA; because that example, 1 milliampere can be composed as 1 mA.


The ampere, commonly referred to as an "amp," is the electrical current continuous equal come the flow of one coulomb per second.

The ampere to be previously identified as a consistent current that when passed through two straight and parallel conductors that space spaced one meter apart, will create a force equal to 0.0000002 newtons every meter of length.

In 2019, the ampere was redefined as the electric current matching to the circulation of 1/(1.602 176 634 × 10-19) primary school charges every second.<1>

The ampere is the SI base unit for electric present in the metric system. An ampere is sometimes likewise referred to together an amp. Amperes can be abbreviated together A; for example, 1 ampere can be composed as 1 A.

Ohm"s legislation states the current in between two point out on a conductor is proportional come the voltage and inversely proportional to the resistance. Making use of Ohm"s Law, it"s feasible to express the current in amperes together an expression using resistance and also voltage.
