Try out our MB to GB converter, which allows you to seamlessly convert from megabytes to gigabytes and vice versa. Continue reading to learn:

  • What megabytes and gigabytes are;
  • What the MB to GB conversion is;
  • The base-2 and base-10 conversions and the difference between these units.

You can switch between these variants using our MB to GB converter.

✅ The MB to GB calculator works in both directions. To find how many megabytes are in a gigabyte, enter your value in megabytes. However, to solve the problem of converting 16 GB to MB, you need to fill in the field labeled gigabytes. It's that easy!

If you need to work with kilobytes as well, we invite you to check the kB to MB converter, which we designed precisely for this purpose.

What is a megabyte?

A megabyte is a multiple of the unit byte, which measures the amount of data stored in a digital medium. There are two definitions of how many bytes 1 megabyte has.

First, let's talk about the base-2 definition. According to information technology fields, 1 MB is equal to 10242 bytes. You may ask why the 1024 base is used since the 1000 base is usually used for converting multiples of units with prefixes such as kilo and mega.

In the computer world, the binary (aka base-2 number system) is used for representing data. Because of this, it has made more sense to use the power of 2 when referring to computer information, and 1024 is, in fact, equal to 210. Base-2 is the representation used by the Microsoft Windows operating system for computer memory, such as RAM.

On the other hand, the base-10 definition states that 1 MB is equal to 10002 bytes, which in turn equals 1,000,000 bytes. Here, the standard 1000 base is used to convert to bytes. This definition follows the rules of the SI metric system. It is commonly used in the context of disk sizes (such as hard drives) and computer networking.

As you see, there is more than one definition of a megabyte. To resolve this ambiguity, the International Electrotechnical Commission (IEC) introduced the mebibyte unit (MiB), which is synonymous with the base-2 definition of megabyte:

1 MiB = 10242 bytes

However, there are times when it can still be challenging to figure out whether a megabyte represents 10242 bytes or 10002 bytes. That's why our GB to MB calculator does both conversions.

What is a gigabyte?

Like a megabyte, a gigabyte is a multiple of the byte unit. The only difference is the power, which designates how many bytes each unit has. The binary definition of the gigabyte states that 1 GB is equal to 10243 bytes, while the SI metric system says that 1 GB is equal to 10003 bytes.

Is a GB bigger than a MB?

Yes, a gigabyte is bigger than a megabyte. In fact, a gigabyte is either 1000 or 1024 times a megabyte. The difference depends on the selected numeral system used. In the base-10 system, 1 GB equals 1000 MB, while in the base-2 system, 1 GB equals 1024 MB.

Is it still unclear to you how the MB to GB conversion works? Let us dive into it with several examples or practice the calculations with the MB to GB converter.

How do you convert MB to GB? MB to GB conversion

As we have already explained, the conversion from megabytes to gigabytes is pretty easy. In the next two sections, you will learn how to convert MB to GB using the base 2 and base 10 number systems.

Base-2: non-SI system

In the case of a base-2 system, to get the number of gigabytes, you should divide the number of megabytes by 1024.

For example, when converting 2048 megabytes to gigabytes, the result is 2048/1024, which is equal to 2. Here is the formula:

GB=MB/1024\mathrm{GB} = \mathrm{MB} / 1024

Here are some examples of megabytes to gigabytes conversions using the base-2 system:

  • 512 MB = 0.5 GB
  • 1024 MB = 1 GB
  • 2560 MB = 2.5 GB
  • 4096 MB = 4 GB

A more tricky conversion would be 1000 MB to GB:
1000 MB = 0.9766 GB

Base-10: SI system

If you want to get the number of gigabytes from megabytes when using the base-10 system, you should divide the number of megabytes by 1000. Here is the formula:

GB=MB/1000\mathrm{GB} = \mathrm{MB} / 1000

According to the base-10 system:

  • 500 MB = 0.5 GB
  • 1000 MB = 1 GB
  • 2500 MB = 2.5 GB
  • 4000 MB = 4 GB

What about converting 16 GB to MB? In that case, you need to multiply GB by 1000.

So 16 GB = 16,000 MB

Be sure to try our MB to GB converter, which allows you to easily switch between MB and GB in both base-2 and base-10 systems. You can also check the Mbps to Gbps converter to convert between different data transfer rates instead of static media storage!

FAQs

How many bytes are in a gigabyte?

There are 1,000,000,000 (109) or 1,073,741,824 bytes in a gigabyte.

The answer to the question of how many bytes are in a gigabyte depends on the system used:

Base-2 system:
1 GB = 10243 bytes = 1,073,741,824 bytes

Base-10 system:
1 GB = 10003 bytes = 1,000,000,000 bytes

How many bytes are in a megabyte?

There are 1,000,000 (106) or 1,048,576 bytes in a megabyte. The chosen definition determines the exact number:

Using the base-2 system:
1 MB = 10242 bytes = 1,048,576 bytes

Using the base-10 system:
1 MB = 10002 bytes = 1,000,000 bytes

How many megabytes are in a gigabyte?

There are 1000 or 1024 megabytes in a gigabyte. To convert 1 GB to MB, select the number system:

  • Base-2 system: 1 GB = 1024 MB
  • Base-10 system: 1 GB = 1000 MB

How do I convert GB to MB?

To do the GB to MB conversion, follow the below steps:

  1. Choose the base you want to work with, base 2 or base 10.
  2. If you selected base 2, multiply the value in GB by 1024.
  3. If you selected base 10, multiply the value in GB by 1000.
  4. The resulting number is your value in MB.
