Megabytes divided by 1,024.

How MB to GB conversion works

This calculator uses the common computer-storage convention that 1 gigabyte equals 1,024 megabytes.

It divides megabytes by 1,024 to estimate gigabytes.

Some storage vendors use decimal marketing units where 1 GB is treated as 1,000 MB. This page uses the 1,024-based convention and states that assumption.

Useful next steps

MB to GB formula

Gigabytes = Megabytes / 1024

Divide megabytes by 1,024 to convert to gigabytes.

  • Megabytes is the starting file size or storage amount.
  • 1,024 is the number of megabytes in one gigabyte under this convention.
  • Gigabytes is the converted storage amount.

What the Numbers Mean

Megabytes
A data-size unit often used for images, apps, documents, and smaller downloads.
Gigabytes
A larger data-size unit often used for storage plans, device capacity, and large downloads.
1024-based convention
This calculator uses 1 GB = 1,024 MB, which is common in computing contexts.

Assumptions

  • The calculator uses 1 GB = 1,024 MB.
  • Negative file sizes are not allowed.
  • Storage vendors and operating systems may display capacity using different conventions.
  • Round based on whether you need a rough estimate or a technical storage comparison.

Worked Examples

512 MB to GB

Input
512 MB
Formula

0.5 GB

512 MB is half of a 1,024 MB gigabyte.

1,024 MB to GB

Input
1,024 MB
Formula
1024 / 1024
Output
1 GB

Under the 1,024-based convention, 1,024 MB equals 1 GB.

2,048 MB to GB

Input
2,048 MB
Formula
2048 / 1024
Output
2 GB

This is common for app storage or download bundles.

5,120 MB to GB

Input
5,120 MB
Formula
5120 / 1024
Output
5 GB

Larger file groups convert cleanly when they are multiples of 1,024.

Practical MB to GB Examples

MB-to-GB conversion is most useful when file totals need to be compared with storage limits.

Download size

3,500 MB game update

3.418 GB

A download shown in MB can be compared with a GB storage limit.

Phone storage

8,192 MB of videos

8 GB

Media folders often convert neatly into gigabytes.

Cloud upload

750 MB project folder

0.7324 GB

This helps estimate how much of a cloud storage plan the upload uses.
