Convert Megabytes to Gigabytes
1 megabyte is 0.001 GB. One megabyte is exactly 0.001 gigabytes.
One megabyte is 0.001 gigabytes. To convert megabytes to gigabytes, multiply by 0.001; to go the other way, divide by 0.001 or multiply by 1000. The factor is exact rather than rounded: it follows from IEC 80000-13. Exactly one million bytes.

What are megabytes and gigabytes?
- Megabyte (MB)
- Exactly one million bytes. A file manager showing a smaller number for the same file is counting in mebibytes.
- Gigabyte (GB)
- Exactly one billion bytes. This is why a "1 TB" drive shows as roughly 931 GB in Windows: the drive is sold in decimal and displayed in binary.
