Kiloampere [kA] to Ampere [A] Converter

Quick Reference

1 Kiloampere (kA) = 1000 Ampere (A)

1 Ampere (A) = 0.001 Kiloampere (kA)

How to Convert Kiloampere to Ampere

1 kA = 1000 A
1 A = 0.001 kA

To convert Kiloampere to Ampere, multiply the value by 1000. To convert Ampere back to Kiloampere, divide by 1000.

Example: convert 10 kA to A:
10 kA = 10 x 1000 = 10000 A

↔ Convert Ampere to Kiloampere

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.

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 [kA] to Ampere [A] Converter

What is 1 kA in A?
1 Kiloampere (kA) equals 1,000 A, and 1 A equals 0.001 kA.
How do I convert Kiloampere to Ampere?
Multiply by 1,000: 10 kA × 1,000 = 10,000 A. The converter above does it for any value, with the precision you choose.
What is 100 kA in A?
100 kA = 100,000 A. Common amounts are listed on this page, each with its own step-by-step page.
Is a Kiloampere bigger than a Ampere?
Yes. 1 kA = 1,000 A, so the same quantity becomes a larger number when written in A.
