To convert from megahertz (MHz) to hertz (Hz), use the following formula:
Let's convert 5 megahertz (MHz) to hertz (Hz).
Using the formula:
Therefore, 5 megahertz (MHz) is equal to hertz (Hz).
Here are some quick reference conversions from megahertz (MHz) to hertz (Hz):

A megahertz (MHz) is a unit used to measure frequency, and it's equal to one million hertz (Hz).
Think of it as a way of counting how many times something happens per second. You'll encounter this measurement in various parts of modern technology, from your car radio to the computer on your desk.
Megahertz is the standard unit for measuring radio frequency, especially for FM (Frequency Modulation) radio.
When you tune your radio to a station like "98.7 FM," you're actually selecting a specific broadcast frequency of 98.7 megahertz.
Each station in the FM broadcast band (which typically spans 88 to 108 MHz) is assigned its own unique frequency.
This prevents signals from overlapping and interfering with each other, allowing your radio to isolate and play the desired station clearly.
In the world of computer processors (CPUs), it's a common misconception that a higher megahertz (MHz) or gigahertz (GHz) rating automatically means better processor performance.
This concept is often referred to as the "megahertz myth."
While clock speed (the rate at which a processor executes instructions, measured in MHz or GHz) is a part of the puzzle, it isn't everything.
A modern processor's overall speed and efficiency depend more on other key factors, such as:
Because of this, a newer processor with a lower clock speed but a more advanced design can easily outperform an older one with a higher clock speed.
The unit "hertz," and by extension megahertz, is named in honor of the German physicist Heinrich Hertz.
In the late 1880s, Hertz was the first person to definitively prove the existence of electromagnetic waves—something that had only been a theory until then.
His foundational work paved the way for nearly all modern wireless technology, including radio, television, and Wi-Fi. Naming the unit of frequency after him is a tribute to his groundbreaking discoveries.
Hertz (Hz) is the standard unit of frequency, measuring the number of cycles per second.
You encounter it everywhere in modern technology, from the sound you hear and the screen you're looking at to the speed of your computer's processor (CPU). The plural form is simply hertz.
The unit is named in honor of the German physicist Heinrich Rudolf Hertz.
In the late 1880s, he was the first person to provide conclusive proof of the existence of electromagnetic waves. His groundbreaking experiments laid the groundwork for the development of radio, television, and all forms of wireless communication.
Hertz is a fundamental measurement you encounter in everyday technology, often without realizing it. Here are two of the most common examples:
A sound's pitch is determined by its frequency (measured in hertz): higher frequencies produce higher pitches.
For example, the A above middle C on a piano is standardized at 440 Hz.
The refresh rate of your computer monitor, TV, or smartphone screen is measured in hertz.
This number indicates how frequently the display updates the image per second—a higher value results in smoother motion, which is especially noticeable in videos and gaming.
When discussing computer processors, you often hear the term gigahertz (GHz). One gigahertz is equal to one billion hertz (1 GHz = 109 Hz).
This value represents the processor's CPU clock speed—the number of processing cycles it can execute per second.
Before gigahertz became the standard, speeds were often measured in megahertz (MHz), where 1 GHz equals 1,000 MHz. While not the sole indicator of performance, a higher clock speed generally means a processor can perform calculations and execute instructions more quickly.
