This article will show how to convert electric current measurement units from kiloamperes (kA) to nanoamperes (nA). We will cover essential definitions, provide examples, share relevant formulas, and present tables, along with answers to common questions.
Definitions of Ampere, Kiloampere, and Nanoampere
Let’s get started by understanding the key definitions of Ampere (A), Kiloampere (kA), and Nanoampere (nA). 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 thousandth of a kiloamperes (10-6 kA or 1/1,000 kA).
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.
What is Nanoampere?
A nanoampere (nA) is a unit of electric current in the SI system equal to one billionth (1/1,000,000,000) of an ampere (10-9 A).
It represents an extremely small current level, commonly used in fields where precise measurements are necessary, such as semiconductor testing, quantum computing, nanotechnology research, and biomedical sensors, where minimal electric current variations must be accurately captured and analyzed.
kA to nA 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 kilo- prefix in the International System of Units (SI) represents a multiplier of 103 (1,000) while the nano- represents a multiplier of 10-9 (0.000000001).
So, to convert from kiloamps to nanoamps, multiply the number of kiloamps (I(kA)) by 1012 (1,000,000,000,000).
I(nA) = I(kA) × 1012 = I(kA) × 1,000,000,000,000
Or remember the kA-to-nA conversion factor: 1 kA = 1012 = 1,000,000,000,000 nA

Examples
Now, let's look at an example that illustrates the calculations required to convert from kiloamperes to nanoamperes (kA to nA).
Example: Heavy-Duty Electric Motor Analysis Scenario
Heavy-duty electric motors typically run on currents measured in kiloamperes. For detailed noise and fluctuation studies, their current is converted to nanoamperes.
If a motor runs at 1.8 kA, what is the equivalent current in nanoamperes? You need it to analyze fine-scale variations in motor control circuits.
Solution
Since 1 kiloampere (kA) = 1012 = 1,000,000,000,000 nanoamperes (nA), we can convert 1.8 kA to nanoamperes by using the following formula:
Therefore, the 1.8 kA electric current is equivalent to 1,800,000,000,000 nA.
To solve the problem with our calculator, follow the steps below:

FAQs
Is 1 kiloampere or 1 nanoampere larger?
A kiloampere (kA) is a trillion times bigger than a nanoampere (nA). Here are the relationships between the units:
1 kA = 1012 = 1,000,000,000,000 nA1 nA = 10-12 = 1 ÷ 1,000,000,000,000 = 0.000000000001 kA
How to convert from kiloamperes to nanoamperes?
To convert electric current from kiloamperes (kA) to nanoamperes (nA), follow these simple steps:
- Write down the electric current value in
kiloamperes (kA). - Multiply it by the value of a

Why do I need to convert kiloamperes to nanoamperes?
Converting kiloamperes to nanoamperes allows you to view large currents on a much finer scale. This is important when high-resolution instruments detect subtle variations or noise in a system.
It also helps in integrating data from different measurement systems, ensuring that both large-scale and minute current changes can be compared accurately.
