Milliampere [mA] to Kiloampere [kA] Converter
Quick Reference
1 Milliampere (mA) = 1.0000e-6 Kiloampere (kA)
1 Kiloampere (kA) = 1000000 Milliampere (mA)
How to Convert Milliampere to Kiloampere
1 mA = 0.000001 kA
1 kA = 1000000 mA
To convert Milliampere to Kiloampere, divide the value by 1000000 (equivalently, multiply by 1.0000e-6). To convert Kiloampere back to Milliampere, multiply by 1000000.
Example: convert 10 mA to kA:
10 mA = 10 x 0.000001 = 0.000009999999999999999 kA
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.
Kiloampere
Definition: A kiloampere (kA) is a unit of electric current equal to one thousand (10³) amperes. It is a multiple 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 kiloampere, as a decimal multiple of the ampere, was derived as a larger unit for measuring very high currents, such as those found in industrial applications or lightning strikes.
Current use: Kiloamperes are used to measure high currents in applications like power transmission, welding, circuit breakers, and lightning protection systems. It is a convenient unit for expressing the magnitude of these large currents.
