Convert megahertz to hertz
Converting megahertz to hertz 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 1,000,000 Hz, 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 hertz
To convert megahertz to hertz, multiply the number of megahertz by 1,000,000. For example, 10 MHz × 1,000,000 = 10,000,000 Hz.
Hz = MHz × 1,000,000
- Write down the value in megahertz you want to convert.
- Multiply it by 1,000,000 (the exact MHz→Hz factor).
- The result is your value in hertz. 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.
Hertz (Hz). The hertz is the SI unit of frequency: one cycle per second. It is named after Heinrich Hertz and measures everything from mains electricity (50–60 Hz) to musical pitch.
Frequently asked questions
How do I convert megahertz to hertz?
To convert megahertz to hertz, multiply the number of megahertz by 1,000,000. For example, 10 MHz × 1,000,000 = 10,000,000 Hz. Or skip the math: type the value into the converter at the top of this page and the result updates instantly.
How many hertz are in 1 megahertz?
1 MHz = 1,000,000 Hz. That is the fixed relationship used by this converter and by international standards.
How many megahertz are in 1 hertz?
1 Hz = 0.000001 MHz. If you are converting in the opposite direction, use our Hertz to Megahertz converter for the dedicated table and FAQ.
Is the megahertz to hertz conversion exact?
Yes. Both units are defined by international agreement, so the factor of 1,000,000 is exact. Displayed results are rounded to 6 significant digits only for readability.
What is megahertz used for?
