Convert kilohertz to megahertz
Converting kilohertz to megahertz is a common frequency task, whether you are checking a recipe, a spec sheet, a travel distance or a homework problem. Since 1 kHz equals 0.001 MHz, the math is a single multiplication — and this page does it for you instantly, with the formula, a table of common values and answers to the questions people ask most.
Exact factor
How to convert kilohertz to megahertz
To convert kilohertz to megahertz, multiply the number of kilohertz by 0.001. For example, 10 kHz × 0.001 = 0.01 MHz.
MHz = kHz × 0.001
- Write down the value in kilohertz you want to convert.
- Multiply it by 0.001 (the exact kHz→MHz factor).
- The result is your value in megahertz. Check it below with the converter or the table.

About these units
Kilohertz (kHz). A kilohertz is 1,000 hertz. AM radio broadcasts sit around 500–1,700 kHz, human hearing spans roughly 20 Hz to 20 kHz, and audio sample rates are quoted in kHz.
Megahertz (MHz). A megahertz is one million cycles per second. FM radio occupies 88–108 MHz, and older CPU clocks, memory buses and shortwave bands are measured in MHz.
Frequently asked questions
How do I convert kilohertz to megahertz?
To convert kilohertz to megahertz, multiply the number of kilohertz by 0.001. For example, 10 kHz × 0.001 = 0.01 MHz. Or skip the math: type the value into the converter at the top of this page and the result updates instantly.
How many megahertz are in 1 kilohertz?
1 kHz = 0.001 MHz. That is the fixed relationship used by this converter and by international standards.
How many kilohertz are in 1 megahertz?
1 MHz = 1,000 kHz. If you are converting in the opposite direction, use our Megahertz to Kilohertz converter for the dedicated table and FAQ.
Is the kilohertz to megahertz conversion exact?
Yes. Both units are defined by international agreement, so the factor of 0.001 is exact. Displayed results are rounded to 6 significant digits only for readability.
What is kilohertz used for?
