Understanding the Units

What is a Kiloampere?

The ampere is the SI base unit of electric current, defined since 2019 by fixing the elementary charge at exactly 1.602176634 × 10⁻¹⁹ coulombs.

Named after André-Marie Ampère (1775–1836), French mathematician and physicist who founded the science of classical electromagnetism.

Common contexts: electrical engineering, power distribution.
