This article will show how to convert electric current measurement units from gigaamperes (GA) to kiloamperes (kA). We will cover essential definitions, provide examples, share relevant formulas, and present tables, along with answers to common questions.
Definitions of Ampere, Gigaampere, and Kiloampere
Let’s get started by understanding the key definitions of Ampere (A), Gigaampere (GA), and Kiloampere (kA). Understanding these terms will allow you to perform conversions confidently.
What is Ampere?
The ampere (A) is the SI base unit of electric current, representing the amount of charge flowing through a conductor per second.[1] It is defined based on the elementary charge (e), where 1 A = 1 coulomb per second (C/s).
"Amp" is an informal abbreviation commonly used in everyday conversation and electrical contexts, though "A" remains the official SI unit symbol.
According to SI prefixes[2], which are based on powers of 10, an ampere (1 A) is equivalent to one billionth (1/1,000,000,000) of a gigaampere (10-9 GA or 0.000000001 GA).
What is a Gigaampere?
A gigaampere (GA) is a derived unit of electric current in the SI system equal to one billion amperes (1,000,000,000 A).
Gigaamperes are used in extreme scenarios, such as theoretical models in astrophysics, high-energy plasma physics, or advanced experimental setups, where it’s necessary to describe incredibly large currents in a compact and understandable way.
What is a Kiloampere?
A kiloampere (kA) is a derived unit of electric current in the SI system equal to one thousand ampere (1,000 A).
It is typically used in high-power applications and industrial contexts where currents are on a much larger scale than what is encountered in everyday electronic devices. For instance, large-scale power generation, electrical transmission systems, and heavy industrial processes often involve currents measured in kiloamperes.
GA to kA formula
Let’s take a closer look at the conversion formula so you can carry out these conversions independently, whether using a calculator or doing it manually with pencil and paper.
The giga- prefix in the International System of Units (SI) represents a multiplier of 109 (1,000,000,000) while the kilo- represents a multiplier of 103 (1,000).
So, to convert from gigaamps to kiloamps, multiply the number of gigaamps (I(GA)) by 106 (1,000,000).
I(kA) = I(GA) × 106 = I(GA) × 1,000,000
Or remember the GA-to-kA conversion factor: 1 GA = 106 = 1,000,000 kA

Examples
Now, let's look at an example that illustrates the calculations required to convert from gigaamperes to kiloamperes (GA to kA).
Example: Particle Collider Beam Analysis
In advanced particle colliders, transient beam currents can reach into the gigaampere range. Converting these measurements to kA enables precise calculations for beam stability and electromagnetic control systems.
If a collider beam produces 3.5 GA, what is the current in kiloamperes? You need it to ensure compatibility with the control system design.
Solution
Since 1 gigaampere (GA) = 106 = 1,000,000 kiloamperes (kA), we can convert 3.5 GA to kiloamperes by using the following formula:
Therefore, the 3.5 GA electric current is equivalent to 3,500,000 kA.
To solve the problem with our calculator, follow the steps below:
- Enter the value in gigaamperes: For this example, enter

3,500,000 kA.
FAQs
Is 1 gigaampere or 1 kiloampere larger?
A gigaampere (GA) is a million times bigger than a kiloampere (kA). Here are the relationships between the units:
1 GA = 106 = 1,000,000 kA1 kA = 10-6 = 1 ÷ 1,000,000 = 0.000001 GA
How to convert from gigaamperes to kiloamperes?
To convert electric current from gigaamperes (GA) to kiloamperes (kA), follow these simple steps:
- Write down the electric current value in
gigaamperes (GA). - Multiply it by the value of a
GA-to-kAconversion factor:106or1,000,000. - The result of multiplication is the value of the electric current in
kiloamperes (kA).
Why do I need to convert gigaamperes to kiloamperes?
Converting from gigaamperes (GA) to kiloamperes (kA) makes extremely large current values more manageable. Since 1 GA equals 1×106 kA, the conversion scales the numbers down, making them easier to work with in calculations, design specifications, and measurement comparisons.
This conversion is vital in high-energy applications where current values are massive by nature. It helps ensure that the current levels are expressed in a unit that aligns with the ratings of engineering components, simulation models, and safety standards.
You now know how to convert electric current from gigaamperes (GA) to kiloamperes (kA). You can quickly use our calculator to convert between the electric current measurement units to save time for future calculations.
