How to Convert Megahertz to Kilohertz (MHz to kHz)
Frequency conversions apply to radio stations, Wi-Fi bands and processor speeds. This guide shows how to convert megahertz into kilohertz by hand, with examples and a quick-reference table.
The conversion
To convert megahertz to kilohertz, multiply the value by 1,000. To go the other way, divide by the same number (or multiply by 0.001). For a quick estimate, multiply by about 1,000.
Kilohertz = megahertz × 1,000
Worked examples
- 3 MHz = 3,000 kHz
- 12.5 MHz = 12,500 kHz
- 75 MHz = 75,000 kHz

| 5 MHz | 5,000 kHz |
| 10 MHz | 10,000 kHz |
| 20 MHz | 20,000 kHz |
| 25 MHz | 25,000 kHz |
| 50 MHz | 50,000 kHz |
| 100 MHz | 100,000 kHz |
| 250 MHz | 250,000 kHz |
| 500 MHz | 500,000 kHz |
| 1,000 MHz | 1,000,000 kHz |
Common questions
Is MHz to kHz exact?
The factors used here are the internationally defined values where they exist; results are rounded for display only.
How do I convert back?
Use the Kilohertz to Megahertz converter.
Mistakes to avoid
Rounding the factor too early
Using 3 instead of 3.28 for feet per metre introduces an error of almost 9% before you have started.
Mixing similar-sounding units
US and imperial gallons, pints and tons are different sizes, and decimal kilobytes differ from binary kibibytes.
Forgetting squared and cubed units
Area and volume factors are the length factor squared or cubed, so 1 m² is about 10.76 sq ft, not 3.28.
Background
For everyday use, three or four significant figures are usually enough. Engineering, science and trade documents may need more, and rounding should happen only at the end of a calculation.
Writing the units next to every number while you work is the simplest way to avoid mistakes. If the units do not cancel to leave the one you want, the calculation is set up wrongly.
A conversion table is handy for common values, but a calculator is faster and avoids interpolation errors for anything in between.
