megahertz to hertz Conversion Formula

To convert from megahertz (MHz) to hertz (Hz), use the following formula:

 hertz (Hz)\textbf{ hertz} \text{ (Hz)}

=106× megahertz (MHz)= 10^{6}\times \textbf{ megahertz} \text{ (MHz)}

Example

Let's convert 5 megahertz (MHz) to hertz (Hz).

Using the formula:

5×106=50000005 \times 10^{6} = 5000000

Therefore, 5 megahertz (MHz) is equal to 50000005000000 hertz (Hz).

What is a Megahertz (MHz)?

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.

How Does Megahertz Work for FM Radio?

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.

Is a Higher MHz Always Better for Computers?

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:

  • Processor Architecture: The fundamental design and efficiency of the chip.
  • Number of Cores: How many tasks the processor can effectively handle at once.
  • Cache Size: A small amount of super-fast memory built into the processor.

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.

Where Does the Term 'Hertz' Come From?

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.

What Is a Hertz (Hz)?

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.

Who Was Heinrich 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.

What Is Hertz Used For in Everyday Technology?

Hertz is a fundamental measurement you encounter in everyday technology, often without realizing it. Here are two of the most common examples:

Sound Waves and Pitch

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.

Screen Refresh Rates (60 Hz vs. 120 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.

  • 60 Hz: Updates the image 60 times per second. This is the standard for most displays.
  • 120 Hz: Updates 120 times per second for much smoother on-screen movement, making it great for gaming.
  • 240 Hz: Updates 240 times per second, offering exceptionally fluid motion for professional and competitive gamers.

What Does Gigahertz (GHz) Mean for Computers?

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.

What is the International System of Units (SI)?

The International System of Units (SI) is the modern form of the metric system and the most widely used system of measurement in the world. It is founded on seven fundamental units: the second (time), meter (length), kilogram (mass), ampere (electric current), kelvin (thermodynamic temperature), mole (amount of substance), and candela (luminous intensity).
