How to convert Milliamperes to Amperes

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

because one ampere is same to 1,000 milliamperes, you deserve to use this simple formula come convert:

Milliamperes and also amperes room both units offered to measure electric current. Keep reading to learn much more about every unit the measure.

Milliamperes

One milliampere is same to 1/1,000 of an ampere, i beg your pardon is the electrical existing equal come the flow of one coulomb per second.

The milliampere is a many of the ampere, i beg your pardon is the SI basic unit for electrical current. In the metric system, "milli" is the prefix for 10-3. A milliampere is sometimes also referred to together a milliamp. Milliamperes have the right to be abbreviated as mA; because that example, 1 milliampere have the right to be created as 1 mA.

Amperes

The ampere, typically referred to together an "amp," is the electrical current continuous equal come the circulation of one coulomb every second.

The ampere was previously identified as a constant current that once passed with two straight and also parallel conductors that space spaced one meter apart, will create a force equal come 0.0000002 newtons per meter of length.

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

The ampere is the SI base unit because that electric existing in the metric system. One ampere is sometimes likewise referred to as an amp. Amperes have the right to be abbreviated together A; for example, 1 ampere deserve to be created as 1 A.

Ohm"s legislation states the current between two clues on a conductor is proportional come the voltage and also inversely proportional to the resistance. Using Ohm"s Law, it"s feasible to to express the current in amperes together an expression utilizing resistance and also voltage.

IA = VVRΩ

The existing in amperes is equal to the potential distinction in volts split by the resistance in ohms.
