This article will show how to convert electrical resistance measurement units from ohms (Ω) to kiloohms (kΩ). We will cover essential definitions, provide examples, share relevant formulas, and present tables, along with answers to common questions.
Definitions of Ohm and Kiloohm
Let’s get started by understanding the key definitions of Ohm (Ω) and Kiloohm (kΩ). Understanding these terms will allow you to perform conversions confidently.
What is Ohm?
The ohm (Ω) is the SI derived unit of electrical resistance. It is defined as the resistance between two points of a conductor when a constant potential difference of one volt is applied across those points, producing a current of one ampere in the conductor, assuming no additional electromotive force is present.[1]
According to SI prefixes[2], which are based on powers of 10, an ohm (1 Ω) is equivalent to one thousandth (1/1,000) of a kiloohm (10-3 kΩ or 0.001 kΩ).
What is Kiloohm?
A kiloohm (kΩ) is a unit of electrical resistance in the SI system equal to one thousand (1,000) ohms (103 Ω).
It is commonly used in electronics design, industrial sensor calibration, and audio equipment circuitry, where resistor values in the thousands of ohms simplify component labeling, schematic readability, and precision measurements.
Ω to kΩ 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). So, to convert from ohms to kiloohms, divide the number of ohms (R(Ω)) by 103 (1,000).
R(kΩ) = R(Ω) ÷ 103 = R(Ω) ÷ 1,000
Or remember the Ω-to-kΩ conversion factor: 1 Ω = 10-3 = 0.001 kΩ

Examples
Now, let's look at an example that illustrates the calculations required to convert from ohms to kiloohms (Ω to kΩ).
Example: Audio Filter Resistor Design
An audio amplifier uses a resistor whose value is measured in ohms. Converting this value to kiloohms simplifies the documentation and design calculations.
If a resistor measures 4,700 Ω, what is its value in kiloohms? You need it to verify the amplifier circuit design.
Solution
Since 1 kiloohm (kΩ) = 103 = 1,000 ohms (Ω), we can convert 4,700 Ω to kiloohms by using the following formula:
Therefore, the 4,700 Ω electrical resistance is equivalent to 4.7 kΩ.
To solve the problem with our calculator, follow the steps below:
- Enter the value in ohms: For this example, enter
4,700into the From box. - View the result: The converter instantly calculates and displays the equivalent value in kiloohms:
4.7 kΩ.
FAQs
Is 1 ohm or 1 kiloohm larger?
A kiloohm (kΩ) is a thousand times bigger than an ohm (Ω). Here are the relationships between the units:
1 kΩ = 103 = 1,000 Ω1 Ω = 10-3 = 1 ÷ 1,000 = 0.001 kΩ
How to convert from ohms to kiloohms?
To convert electrical resistance from ohms (Ω) to kiloohms (kΩ), follow these simple steps:
- Write down the electrical resistance value in ohms
(Ω). - Multiply it by the value of a
Ω-to-kΩconversion factor:10-3or0.001. - The result of multiplication is the value of the electrical resistance in
kiloohms (kΩ).
Why do I need to convert ohms to kiloohms?
Kiloohms simplify common electronics work where resistor values often hit the thousands, turning cluttered numbers like "47,000 Ω" into clean "47 kΩ" that matches component labels, schematics, and multimeter readings, making designs faster to interpret and less prone to errors.
You now know how to convert electrical resistance from ohms (Ω) to kiloohms (kΩ). You can quickly use our calculator to convert between the electric resistance measurement units to save time for future calculations.
