GB to MB

How many megabytes are in a number of gigabytes.

Decimal: 1 KB = 1,000 bytes, 1 MB = 1,000,000 bytes, 1 GB = 1,000,000,000 bytes, 1 TB = 1,000,000,000,000 bytes.

1000 MB

Examples

The conversion

Multiply the GB value by 1,000. 2 GB is 2,000 MB. 2 GiB is 2,048 MiB.

Which system to use

Use decimal KB, MB, and GB when you are matching a label that counts by thousands. Use binary KiB, MiB, and GiB when a spec counts by 1,024. Do not add the two together as if they were the same unit.
