Related Frequency Units

What Are Megahertz and Hertz?

Hertz (Hz)
The hertz is the SI unit of frequency, named after Heinrich Hertz. One hertz represents one cycle per second. It measures how many times an event occurs within one second, such as wave oscillations, CPU clock cycles, or sound vibrations.
Megahertz (MHz)
A megahertz equals one million hertz (10⁶ Hz). This unit measures higher frequencies commonly found in radio transmissions, computer processors, and wireless communications. The prefix “mega” denotes a factor of one million.
Real-World Applications
Radio Broadcasting: FM radio stations broadcast between 88-108 MHz (88,000,000-108,000,000 Hz).

Computer Processors: Modern CPUs operate at frequencies between 1,000-5,000 MHz (1-5 GHz).

Wireless Communications: WiFi routers use 2,400 MHz and 5,000 MHz bands for data transmission.

Medical Equipment: Ultrasound devices operate at frequencies from 1-20 MHz for imaging purposes.

Frequently Asked Questions

How many hertz are in one megahertz?
One megahertz equals exactly 1,000,000 hertz. The prefix “mega” means one million, so 1 MHz = 1,000,000 Hz. This conversion factor remains constant for all MHz to Hz calculations.
How do you convert MHz to Hz?
To convert megahertz to hertz, multiply the MHz value by 1,000,000. For example, 5 MHz × 1,000,000 = 5,000,000 Hz. This works because “mega” represents a multiplier of one million.
What is the difference between MHz and Hz?
Both units measure frequency, but they differ in magnitude. Hertz measures cycles per second, while megahertz measures millions of cycles per second. MHz is more convenient for expressing higher frequencies like radio waves and processor speeds, while Hz is used for lower frequencies like audio.
Why are radio frequencies measured in MHz?
Radio frequencies typically range from hundreds of thousands to billions of hertz. Using megahertz simplifies these large numbers. For example, saying “100 MHz” is more practical than “100,000,000 Hz” when discussing FM radio stations or wireless communications.
Can I convert GHz to Hz through MHz?
Yes, you can convert gigahertz (GHz) to hertz via megahertz. First, convert GHz to MHz by multiplying by 1,000 (since 1 GHz = 1,000 MHz). Then convert MHz to Hz by multiplying by 1,000,000. For example, 2 GHz = 2,000 MHz = 2,000,000,000 Hz.
What frequencies are commonly measured in MHz?
Common applications include: FM radio (88-108 MHz), amateur radio bands (1.8-1300 MHz), WiFi 2.4 GHz band (2400 MHz), older computer processors (before GHz era), RF communication devices (315, 433, 915 MHz), and GPS signals (1575.42 MHz).
Is MHz bigger than Hz?
Yes, megahertz is significantly larger than hertz. One MHz equals one million Hz, making MHz 1,000,000 times larger. This makes MHz suitable for measuring high-frequency phenomena like radio waves, while Hz works better for lower frequencies like sound waves.
How do MHz relate to wavelength?
Frequency (MHz) and wavelength have an inverse relationship. As frequency increases, wavelength decreases. The formula is: wavelength (meters) = speed of light (299,792,458 m/s) ÷ frequency (Hz). A 100 MHz signal has a wavelength of approximately 3 meters in free space.
