## How to Convert Amperes to Milliamperes

To convert a ampere measurement to a milliampere measurement, multiply the electric current by the conversion ratio. One ampere is equal to 1,000 milliamperes, so use this simple formula to convert:

The electric current in milliamperes is equal to the amperes multiplied by 1,000.

**For example,**here's how to convert 5 amperes to milliamperes using the formula above.

Amperes and milliamperes are both units used to measure electric current. Keep reading to learn more about each unit of measure.

## Amperes

The ampere, commonly referred to as just "amp," is the electrical current constant equal to the flow of one coulomb per second. According to an SI brochure, the ampere is a constant current that when passsed through two straight and parallel conductors that are spaced one meter apart, will produce a force equal to 0.0000002 newtons per meter of length.

The ampere is the SI base unit for electric current in the metric system. A ampere is sometimes also referred to as an amp. Amperes can be abbreviated as *A*, for example 1 ampere can be written as 1 A.

Ohm's Law states the current between two points on a conductor is proportional to the voltage and inversely proportional to the resistance. Using Ohm's Law, it's possible to express the current in amperes as an expression using resistance and voltage.

I_{A} = V_{V}R_{Ω}

The current in amperes is equal to the potential difference in volts divided by the resistance in ohms.

## Milliamperes

One milliampere is equal to 1/1,000 of an ampere, which is the electrical current equal to the flow of one coulomb per second.

The milliampere is a multiple of the ampere, which is the SI base unit for electric current. In the metric system, "milli" is the prefix for 10^{-3}. A milliampere is sometimes also referred to as a milliamp. Milliamperes can be abbreviated as *mA*, for example 1 milliampere can be written as 1 mA.
