How to convert gigabytes to megabytes
1 gigabyte = 1,000 megabytes. To convert gigabytes to megabytes, multiply by 1,000. A gigabyte is 1,000,000,000 bytes under the SI definition (a gibibyte, GiB, is 1,073,741,824 bytes). A megabyte is 1,000,000 bytes under the SI definition (a mebibyte, MiB, is 1,048,576 bytes).
Worked examples
- 1.5 gigabytes = 1,500 MB (1.5 × 1,000)
- 5 gigabytes = 5,000 MB (5 × 1,000)
- 64 gigabytes = 64,000 MB (64 × 1,000)
Where this conversion comes up
Gigabytes are used for phone storage, RAM, games and mobile data plans; megabytes for photos, songs, app downloads and data plans. Multiply by 1,000: a 1.5 GB video is 1,500 MB (1,536 MB in binary). A 5 GB data plan at roughly 4 MB per minute of standard-definition video covers about 20 hours.
Quick estimate
Multiply by 1,000 (binary: by 1,024).
Common mistakes
- Dividing instead of multiplying. A megabyte is smaller than a gigabyte, so the number of megabytes must come out larger: 1.5 gigabytes = 1,500 MB.
- Mixing decimal and binary units. Drive makers and this page use 1,000-based (SI) units; Windows reports 1,024-based sizes, which is why a 1 TB drive shows as 931 GB. The result box shows both.
