How to use it
- Type the value in the megohms box.
- Read the result in kilohms as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
kΩ = MΩ × 1,000
Multiply the value in megohms by 1,000 to get kilohms.
Example
To convert 25 MΩ to kilohms: 25 × 1,000 = 25,000 kΩ.

About the units
- Megohm
- A megohm is exactly one million ohms, used in cable and motor insulation testing and high input resistances.
- Kilohm
- A kilohm is exactly 1000 ohms, the most common range on electronic resistors such as 4.7 kΩ and 10 kΩ.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many kilohms are in one megohm?
1 MΩ = 1,000 kΩ exactly.
How do I convert megohms to kilohms?
Use kΩ = MΩ × 1,000. For example, 25 MΩ = 25,000 kΩ.
How many megohms are in one kilohm?
1 kΩ = 0.001 MΩ.
What does the k in a resistor value mean?
It means kilo, or 1000, so a 4.7k resistor is 4700 ohms. Schematics sometimes write the same value as 4K7.
How do I work out resistance from voltage and current?
Use Ohm's law: resistance equals voltage divided by current. 12 V with 0.5 A means 24 ohms.
