How to Convert Ampere to KiloampereKiloampere
1 A = 0.001 kA
1 kA = 1000 A
Example: convert 24 A to kA:
24 A = 24 x 0.001 = 0.024 kA
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.
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.
