Ampere [A] to Milliampere [mA] Converter
Quick Reference
1 Ampere (A) = 1000 Milliampere (mA)
1 Milliampere (mA) = 0.001 Ampere (A)
How to Convert Ampere to Milliampere
1 A = 1000 mA
1 mA = 0.001 A
To convert Ampere to Milliampere, multiply the value by 1000. To convert Milliampere back to Ampere, divide by 1000.
Example: convert 10 A to mA:
10 A = 10 x 1000 = 10000 mA
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.
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.
