Gigabytes to Megabytes

Type in either box. The formula, a table and every other unit are below.

Other units

kB, MB, GB and TB are powers of 1000 (what drives and networks advertise). KiB, MiB, GiB and TiB are powers of 1024 (what many operating systems actually show).

How to convert

1 GB = 1000 MB

MB = GB × 1000

Example: 10 GB = 10000 MB

Quick mental math. Drives and networks count 1 GB as 1,000 MB. Many operating systems count in 1,024s and call that unit a GiB (1 GiB = 1,024 MiB).
