How to convert gigabytes to megabytes

1 GB = 1,000 MB

1 GB = 1,000 MB exactly, because SI prefixes are powers of 10 (SI Brochure): multiply GB by 1,000. The binary pair differs: 1 GiB = 1,024 MiB exactly (NIST).

Examples

  • 64 GB = 64,000 MB: a phone storage tier
  • 2 GB = 2,000 MB: a small mobile data allowance
  • 1.5 GB = 1,500 MB: a film download

Common mistakes

  • Device capacities use decimal GB, so a 64 GB device holds 64,000 MB before formatting; usable space is lower because the system and formatting take some.

Frequently asked questions

What is 2 GB in MB?

2 GB is 2,000 MB in decimal units, the convention storage makers use. Counted in binary units, 2 GiB is 2,048 MiB.

Why does my computer say 1 GB is 1,024 MB?

It is counting in binary units: 1 GiB (gibibyte) is 1,024 MiB, while 1 GB is 1,000 MB. Some software shows binary results with decimal labels, which causes the mismatch.

How many MiB are in 1 GB?

Exactly 953.67431640625 MiB, or about 953.67. One gigabyte is 1,000,000,000 bytes and one mebibyte is 1,048,576 bytes.
