1 MHz = 106 Hz = 1000000 Hz
What is Megahertz ?
A megahertz (MHz) is a unit of frequency that equals one million cycles per second. It’s commonly used to measure the frequency of electromagnetic waves, including radio waves and microwaves.
In computing, megahertz is often used to denote the clock speed of a CPU (central processing unit), indicating how many millions of instructions or operations the CPU can execute per second.
However, modern processors are typically measured in gigahertz (GHz), which equals one billion cycles per second, or even higher frequencies.
What is Hertz ?
Hertz (Hz) is the unit of frequency in the International System of Units (SI), representing cycles per second. It measures the number of times a phenomenon repeats within one second.
For example, if a sound wave has a frequency of 1000 Hz, it means that the air particles vibrate back and forth 1000 times per second, producing the sensation of sound.
Hertz is used to describe various types of periodic phenomena, including electromagnetic waves, electrical signals, and mechanical vibrations.
Example
In case you have a radio station tuned at a frequency of 98.7 MHz and wish to express it in hertz units, multiplication becomes handy.
It would suffice to multiply the value by 1 million for convenience since every megahertz represents a million hertz.
Calculation: Frequency in Hz = 98.7 MHz * 1000000 Hz/MHz = 98700000 Hz
So, the radio station broadcasts at a frequency of 98700000 Hz.
