Convert megahertz to kilohertz
Converting megahertz to kilohertz is a common frequency task, whether you are checking a recipe, a spec sheet, a travel distance or a homework problem. Since 1 MHz equals 1,000 kHz, 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 megahertz to kilohertz
To convert megahertz to kilohertz, multiply the number of megahertz by 1,000. For example, 10 MHz × 1,000 = 10,000 kHz.
kHz = MHz × 1,000
- Write down the value in megahertz you want to convert.
- Multiply it by 1,000 (the exact MHz→kHz factor).
- The result is your value in kilohertz. Check it below with the converter or the table.

About these units
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.
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.
Frequently asked questions
How do I convert megahertz to kilohertz?
To convert megahertz to kilohertz, multiply the number of megahertz by 1,000. For example, 10 MHz × 1,000 = 10,000 kHz. Or skip the math: type the value into the converter at the top of this page and the result updates instantly.
