hertz to megahertz conversion

How to convert hertz to megahertz?

Certainly! Let's break this down step-by-step.

Converting Hertz to Megahertz

1 hertz (Hz) is a measure of frequency, indicating one cycle per second.

To convert hertz to megahertz (MHz), you'll use the following relationship:

1 megahertz (MHz) = 1,000,000 hertz (Hz)

So, to convert from hertz to megahertz, you divide the number of hertz by 1,000,000.

For example: $1 \text{ Hz} = \frac{1 \text{ Hz}}{1,000,000} = 0.000001 \text{ MHz}$

Real-World Examples of Different Frequencies

1. Very Low Frequencies:

   • 1 Hz (1 cycle per second):
     • Seismic waves generated by natural phenomena like earthquakes often have frequencies around this range.
   • 50 Hz - 60 Hz:
     • The frequency of the alternating current (AC) electricity used in households in many parts of the world (50 Hz in Europe and Asia, 60 Hz in America).

2. Audio Frequencies:

   • 20 Hz - 20,000 Hz (20 kHz):
     • The approximate range of human hearing. For example, the lowest note on a standard piano is about 27.5 Hz, and some dog whistles operate around 20 kHz because dogs can hear higher frequencies than humans.

3. Radio Frequencies:

   • 87.5 MHz - 108 MHz:
     • The range of FM radio broadcasts.

4. Wireless and Telecommunications Frequencies:

   • 2.4 GHz (2,400,000,000 Hz):
     • Frequencies used for Wi-Fi and Bluetooth communications.
   • 3 GHz - 30 GHz:
     • Frequencies used for microwave and satellite communications.

5. Visible Light Frequencies:

   • Approximately 429 THz (terahertz) to 750 THz:
     • Frequencies corresponding to visible light. For example, red light is around 429–484 THz, green light is around 526–606 THz, and violet light is about 668–789 THz.

By understanding these examples, you can see how hertz (Hz), kilohertz (kHz), megahertz (MHz), gigahertz (GHz), and terahertz (THz) play crucial roles in various aspects of science and technology.
