# Gigabyte/Megabyte Conversions

Monday, October 4th, 2010 by | Filed Under: Computer Terms, Digital Photography, Uncategorized

Is there a formula to easily convert megabytes into gigabytes?

Yes there is! You can do the conversion manually by using arithmetic or you can use software to do the conversion for you. First, let’s look at the formula for converting megabytes (Mb) into gigabytes (Gb).

Formula for Megabyte to Gigabyte Conversion

As shown below, the formula is straightforward:

1024 Mb = 1 Gb

Therefore,
1 Mb = 1/1024 Gb = 0.0009765625 Gb

Let’s see how this works with two examples.

Example 1 – Convert Megabytes into Gigabytes

Suppose, you have bought yourself an Argus 3.2MP Digital/PC Camera. This camera comes with 16 Mb internal memory. How much is this in gigabytes? Let’s find out.

1 Mb = 0.0009765625 Gb

Therefore,
16 Mb = 0.0009765625 Gb x 16

16 Mb = 0.015625 Gb

There’s nothing more to it. Now, let’s look at another example.

Example 2 – Convert Gigabytes into Megabytes

Suppose you have bought yourself a new Black 4GB Strontium Flash Drive. As the name suggests, this flash drive has a 4Gb capacity. How much is this in megabytes? Let’s use the formula.

1 Gb = 1024 Mb

Therefore,
4 Gb = 1024 Mb x 4

4 Gb = 4096 Mb

That’s it!

Using Google to Convert Megabytes to Gigabytes

Doing these conversions can be a tedious task, especially if you need to convert odd sounding numerals, like 0.007833 Mb into gigabytes. Fortunately, Google comes with a in-built converter. All you have to do is specify the figures you want to convert in the Search field and then click the Search button, as shown by the image below. The key here is to specify the conversion, so Google understands what you are trying to convert. For example, to convert 128 megabytes to gigabytes, type the following in the search field:

Convert 128 Mb to Gb

As you can see Google, does the conversion for you and displays the results at the top. You can also use the inbuilt Google Calculator for other conversions, such as height, weight, and volume.

### One Response to “Gigabyte/Megabyte Conversions”

1. ron says:

True, but you should also mention the HD manufacturer convention of using decimal instead of binary counts. In that world:
1 GB = 1000 MB

Yes, this discrepancy is a pet peeve of mine. I think both sides should agree on a single convention. I also think it is time for the software world to give up this binary historical “appendix” (appendix as in unneeded organ that periodically gets infected). Our hardware has enough hardware to easily do the binary to decimal conversion for human ease of use. We think decimal, not binary.
