The megahertz
The megahertz (MHz) equals exactly 1,000,000 Hz. It is the standard unit for FM radio broadcast frequencies and early computer processor clock speeds.
Megahertz to Hertz Converter
1 MHz = 1000000 Hz (megahertz → hertz)
1 MHz = 1000000 Hz
1 megahertz equals 1000000 hertz. To convert megahertz to hertz, multiply the megahertz value by 1000000. For quick reference: 1 MHz = 1000000 Hz, 5 MHz = 5000000 Hz, 10 MHz = 10000000 Hz, 100 MHz = 100000000 Hz.
Formula
Hertz = Megahertz × 1000000Quick

Real-world reference
FM radio stations broadcast in the range of 88–108 MHz. Early home computers ran at processor speeds of a few MHz. In hertz, that gives you: 1 MHz = 1000000 Hz, 10 MHz = 10000000 Hz, 100 MHz = 100000000 Hz.
Frequently asked questions
- How many hertz are in 1 megahertz?
- 1 megahertz equals 1000000 hertz.
- How do I convert megahertz to hertz?
- Multiply the megahertz value by 1000000. So x MHz × 1000000 = the equivalent in Hz.
- What is 5 megahertz in hertz?
- 5 megahertz equals 5000000 hertz.
- What is 10 megahertz in hertz?
- 10 megahertz equals 10000000 hertz.
- What is 100 megahertz in hertz?
- 100 megahertz equals 100000000 hertz.
- How do I convert back from hertz to megahertz?
- Multiply the hertz value by 1.0000 × 10^−6. For example, 1 Hz = 1.0000 × 10^−6 MHz.
- Is the megahertz bigger than the hertz?
- Yes. 1 megahertz is larger than 1 hertz — specifically 1000000 times larger.
- Are these conversion factors exact?
- The factor is derived directly from the SI definitions of megahertz and hertz; the displayed value is rounded for readability, and the browser computes using IEEE 754 double-precision arithmetic.
About the megahertz and the hertz
The hertz
The hertz (Hz) is the SI derived unit of frequency, equal to one cycle per second. It is the universal unit for sound pitch, electrical AC frequency, processor clock speed (in multiples), and radio and wireless signal frequencies.
