This article will show how to convert electrical resistance measurement units from megaohms (MΩ) 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, Megaohm, and Kiloohm
Let’s get started by understanding the key definitions of Ohm (Ω), Mega-ohm (MΩ), and Kilo-ohm (kΩ). Understanding these terms will enable you to perform conversions with confidence.
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 millionth (1/1,000,000) of a megaohm (10-6 MΩ or 0.000001 MΩ).
What is Megaohm?
A megaohm (MΩ) is a unit of electrical resistance in the SI system equal to one million (1,000,000) ohms (106 Ω).
It is commonly used in high-voltage insulation testing, medical device safety validation, and industrial sensor design, where measuring extreme resistance up to millions of ohms determines critical safety margins and operational reliability.
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.
MΩ 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 mega- prefix in the International System of Units (SI) corresponds to a multiplier of 106 (1,000,000) while the kilo- prefix represents 103 (1,000).
To convert megaohms (MΩ) to kiloohms (kΩ), multiply the resistance value in megaohms by 103 (1,000,000), since 1 megaohm equals 1,000 kiloohms.
R(kΩ) = R(MΩ) × 103 = R(MΩ) × 1,000
Or remember the MΩ-to-kΩ conversion factor: 1 MΩ = 103 = 1,000 kΩ

Examples
Now, let's look at an example that illustrates the calculations required to convert from megaohms to kiloohms (MΩ to kΩ).
Example: Semiconductor Equipment Quality Control
In semiconductor manufacturing, a wafer insulation test records 3 MΩ of resistance. Converting this to kiloohms aids in fine-tuning the diagnostic reports.
What is 3 MΩ in kiloohms?
Solution
Since 1 megaohm (MΩ) = 1,000 kiloohms (kΩ), we can convert 3 MΩ to kiloohms by using the following formula:
Therefore, the 3 MΩ electrical resistance is equivalent to 3,000 kΩ.
To solve the problem with our calculator, follow the steps below:

FAQs
Is 1 megaohm or 1 kiloohm larger?
A megaohm (MΩ) is a thousand times bigger than a kiloohm (kΩ). Here are the relationships between the units:
1 MΩ = 103 = 1,000 kΩ1 kΩ = 10-3 = 1 ÷ 1,000 = 0.001 MΩ
How to convert from megaohms to kiloohms?
To convert electrical resistance from megaohms (MΩ) to kiloohms (kΩ), follow these simple steps:
- Step 1: Write down the electrical resistance value in megaohms (MΩ).
- Step 2: Multiply it by a thousand (
1,000). - Step 3: The result is the value of the electrical resistance in kiloohms (kΩ).
Why do I need to convert megaohms to kiloohms?
Converting megaohms to kiloohms is useful when you need to work with resistance values on a scale that is easier to manage and compare. For instance, a value expressed in megaohms can sometimes hide small changes or variations that become more apparent when converted to kiloohms.
It also helps to ensure consistency in documentation and compatibility with instruments or diagrams that use kiloohms as the standard unit.
You now know how to convert electrical resistance from megaohms (MΩ) to kiloohms (kΩ). You can quickly use our calculator to convert between electric resistance measurement units, saving time for future calculations.
