Understanding Gigabytes and Megabytes

Gigabytes and megabytes are two commonly used units of digital storage. However, how do they relate to each other?

1 Gigabyte = 1,024 Megabytes (Binary system, used in computing & RAM)
1 Gigabyte = 1,000 Megabytes (Decimal system, used in storage & marketing)

So, if you're asking "1 GB how many MB?", the answer depends on circumstances:

Computers and operating systems 1 GB = 1,024 MB
Storage devices such as an SSD, USB, or HDD, manufacturers will usually state 1 GB = 1,000 MB for simplicity!

Our Gigabytes to Megabytes Converter has automatically calculated both binary and decimal units for you so that you know how much MB you're actually getting!

Conversion Formula

Binary (Computing):

1 GB = 1,024 MB

Decimal (Storage):

1 GB = 1,000 MB

To convert manually:

Megabytes = Gigabytes x 1,024 (binary) or Gigabytes x 1,000 (decimal)

Examples:

4 GB RAM = 4 x 1,024 = 4,096 MB
256 GB SSD = 256 x 1,000 = 256,000 MB
8 GB Movie File = 8 x 1,024 = 8,192 MB

When you are thinking about a 1 GB phone storage, 16 GB flash drive, or 512 GB hard disk, knowing what a 1 GB in MB conversion might help you establish the true amount of storage space.
