What does this tool do?
A gigabyte is 1,000 megabytes in decimal notation and 1,024 mebibytes in binary notation. The difference is small for one file but grows quickly across a large drive.
The Formula
GB = MB ÷ 1,000 (decimal) or ÷ 1,024 (binary)Frequently Asked Questions
How many MB are in a GB?
1,000 MB in decimal notation and 1,024 MiB in binary notation. The binary figure is about 4.9% larger.
Why do upload speeds use MB/s but files show MiB?
Internet providers quote decimal units, while some software reports binary units. Convert both to bytes before comparing them.
