To transform a milliampere measurement come an ampere measurement, divide the electric present by the counter ratio.

since one ampere is equal to 1,000 milliamperes, you deserve to use this an easy formula come convert:

Milliamperes and amperes space both units used to measure electric current. Keep analysis to learn more about each unit the measure.

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

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


The ampere, typically referred to together an "amp," is the electric current consistent equal to the flow of one coulomb per second.

The ampere to be previously defined as a constant current that as soon as passed with two straight and also parallel conductors that room spaced one meter apart, will develop a pressure equal to 0.0000002 newtons per meter the length.

In 2019, the ampere to be redefined together the electric current equivalent to the flow of 1/(1.602 176 634 × 10-19) elementary school charges every second.<1>

The ampere is the SI basic unit because that electric existing in the metric system. An ampere is sometimes also referred to together an amp. Amperes deserve to be abbreviated together A; for example, 1 ampere deserve to be composed as 1 A.

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

The existing in amperes is same to the potential difference in volts separated by the resistance in ohms.
