The gigabyte
The gigabyte (GB) equals 1,000,000,000 bytes. The difference between GB (decimal) and GiB (binary, 1,073,741,824 B) is the reason a '1 TB' drive shows as ~931 GB in Windows.
3000 Gigabytes to Megabytes
3000 GB = 3000000 MB (gigabyte → megabyte)
3000 GB = 3000000 MB
3000 gigabytes (GB) equals 3000000 megabytes (MB). The conversion uses the exact factor 1000: 3000 × 1000 = 3000000.
Formula
Megabytes = Gigabytes × 1000Quick

When to use gigabytes → megabytes
Gigabytes to megabytes multiplies by 1000. Video editors, game installers, and VM disk images are usually MB-precise even when the overall budget is GB-denominated — a 25 GB game install budget is 25 000 MB, useful when a per-asset size list (textures, audio, video cutscenes) needs to be summed and checked against that ceiling before a build ships over the limit.
Software deployment pipelines track this when packaging a release: a container image budget of 2 GB is 2000 MB, and layering tools report individual layer sizes in MB — build engineers sum those layers against the GB-stated registry limit to catch a bloated dependency before a CI push fails at the registry's size cap rather than earlier in the build.

Real-world reference
A standard-definition movie is around 1–2 GB. Phones and laptops typically ship with 128 GB to 2 TB of storage. In megabytes, that gives you: 1 GB = 1000 MB, 10 GB = 10000 MB, 100 GB = 100000 MB.

About the gigabyte and the megabyte
The megabyte
The megabyte (MB) equals 1,000,000 bytes (decimal) or 1,048,576 bytes (binary, formally 'mebibyte' MiB — a roughly 5% difference). Used for music files, photographs, and most everyday document sizes.
