Convert MHz to GHz

Interactive megahertz to gigahertz conversion tool

The MHz to GHz converter below can be used to quickly and easily convert megahertz to gigahertz. Simply enter the number of megahertz you want to convert and the calculator will output the corresponding value in gigahertz.

What is the conversion factor between megahertz and gigahertz?

A conversion factor is used to change the units of a measured quantity without changing its value. It represents the ratio (or fraction) that expresses the relationship between two different units. A conversion factor is always equal to 1.

The relationship between megahertz and gigahertz is 1000, such as:

1 GHz = 1000 MHz

Following the formula above, we can see that there are 1000 megahertz for every gigahertz, and for every megahertz, there are 11000 gigahertz (0.001 GHz).

To convert from megahertz to gigahertz, we turn our formula into a conversion factor that is equal to 1.

1 GHz1000 MHz = 1000 MHz1 GHz= 1

Both these fractions are equal to 1. The numerator and the denominator are equivalent, they are just expressed in different units.

Because we are converting from megahertz to gigahertz, we will use the first fraction: 1 GHz1000 MHz so that megahertz are canceled out. We then multiply the value in megahertz by this fraction to get the result in gigahertz (see example).

Note that MHz is in the denominator (bottom) of the conversion factor. This is important, you always want to have the unit you are converting from at the bottom and the unit you are converting to in the numerator (top).

Conversion factor = Unit you are converting toUnit you are converting from

You will find below how to use this ratio to convert from MHz to GHz. Just remember for now that the conversion factor for converting from megahertz to gigahertz is:

1 GHz1000 MHz

Which is bigger, a megahertz or a gigahertz?

When it comes to measurements, there can be some confusion over which is bigger, a megahertz or an gigahertz. To find out which one is larger, we must first convert one unit to the other and then compare them.

1 MHz = 11000 GHz = 0.001 GHz
0.001 gigahertz is smaller than 1 gigahertz.
1 megahertz is, therefore, smaller than 1 gigahertz.
To be more specific, a gigahertz is 1000 times bigger than a megahertz.

How to convert megahertz to gigahertz?

Multiplying any value by 1 will get you the same value back. You can do that one time or multiple times.

For example:

100 x 1 = 100
400 x 1 x 1 x 1 = 400

Multiplying by 1 is the first step in any unit conversion problem. The second step is to replace the number 1 with the conversion factor that is also equal to 1.

For example, if we want to convert 10000 megahertz into gigahertz we multiply 10000 MHz by the conversion factor of 1 GHz1000 MHz

10000 MHz = 10000 MHz x 1 = 10000 MHz x 1 GHz1000 MHz = 10 GHz

By replacing the number 1 with the conversion factor, megahertz are canceled out and we get the result in gigahertz. And since the conversion factor is equal to 1, multiplying it with the original value won't change its magnitude and will only change its unit.

Based on this, we can conclude that 10000 megahertz are equal to 10 gigahertz.

Remember:

When converting from megahertz to gigahertz, we use 1 GHz1000 MHz as a conversion factor.

Practice: megahertz to gigahertz conversion

Try answering the following questions without using our custom conversion calculator. Knowing how to convert manually between megahertz and gigahertz could prove to be useful, so give it a shot. Once you are confident you can convert megahertz to gigahertz, there is no harm then in taking full advantage of the tools available to you.

How to convert 21 megahertz to gigahertz?

We multiply 21 by the factor of 1

21 MHz = 21 MHz x 1

We replace the number 1 with the conversion factor for megahertz to gigahertz

21 MHz = 21 MHz x 1 GHz1000 MHz

We multiply 21 megahertz by the conversion factor. Having megahertz in the denominator allows us to cancel out the undesired units (MHz) leaving only gigahertz in the final result.

21 MHz = 21 MHz x 1 GHz1000 MHz

21 MHz = 21 x 11000 GHz

21 MHz = 0.021 GHz

Answer: There are 0.021 gigahertz in 21 megahertz

How many gigahertz are in 685 megahertz?

Multiply 685 by the conversion factor. Make sure the unwanted unit (MHz) is in the denominator.

685 MHz = 685 MHz x 1 GHz1000 MHz

This allows us to cancel out the megahertz (MHz) and leave the gigahertz (GHz)

685 MHz = 685 MHz x 1 GHz1000 MHz

685 MHz = 685 x 11000 GHz

685 MHz = 0.685 GHz

Answer: There are 0.685 gigahertz in 685 megahertz
