How to convert megahertz to kilohertz

To convert megahertz to kilohertz, multiply the number of megahertz by 1000.

Formula

kHz = MHz × 1000

Examples

  • 5 MHz = 5 × 1000 = 5000 kHz
  • 25 MHz = 25 × 1000 = 25000 kHz
  • 100 MHz = 100 × 1000 = 100000 kHz

Frequently asked questions

How many kilohertz are in one megahertz?
One megahertz is exactly 1000 kilohertz.
How do I convert kilohertz to megahertz?
To convert kilohertz to megahertz, multiply the number of kilohertz by 0.001. The formula is MHz = kHz × 0.001.
Is this conversion exact?
Yes. Both units have exact definitions and the factor 1000 is exact. Displayed results are only rounded when they have many decimal places.
Which is larger, a megahertz or a kilohertz?
A megahertz is 1000 times larger than a kilohertz. In other words, a kilohertz is exactly 1/1000 of a megahertz.
