How to Convert Milliampere to AmpereAmpere

1 mA = 0.001 A
1 A = 1000 mA

Example: convert 13 mA to A:
13 mA = 13 x 0.001 = 0.013000000000000001 A

Milliampere

Definition: A milliampere (mA) is a unit of electric current equal to one thousandth (10⁻³) of an ampere. It is a subunit of the base unit, the ampere, in the International System of Units (SI).

History/origin: The ampere is named after French physicist André-Marie Ampère. The milliampere, as a decimal multiple of the ampere, was naturally derived as a smaller, more convenient unit for measuring smaller currents. Its usage grew with the development of electronics.

Current use: Milliamperes are commonly used to measure small currents in electronic circuits, portable devices, sensors, and other low-power applications. It is a practical unit for specifying the current requirements and capabilities of components and circuits.

Ampere

Definition: The ampere (symbol: A) is the SI base unit of electric current. It is defined by taking the fixed numerical value of the elementary electric charge e to be 1.602176634 × 10−19 when expressed in the unit C, which is equal to A⋅s.

History/origin: The ampere is named after André-Marie Ampère, a French physicist and mathematician who is considered one of the founders of classical electromagnetism. The current definition was revised in 2019.

Current use: The ampere is fundamental to electrical engineering and electronics. It is used to measure the flow of electric current in circuits, appliances, and power systems worldwide.
