Quick answer: MB to GB Converter
Convert megabytes to gigabytes (binary vs decimal aware if the tool specifies).
Example: 48,000 MB ÷ 1000 → 48 GB marketing; ÷1024 → ~46.9 GiB - explains the gap on your laptop disk view.
Calculations follow the documented formula on this page; rounding and input units can change the last digit-treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
Storage marketing uses decimal GB (10^9), OS often shows binary GiB. Mislabeling causes “where did my 500 GB SSD go?” confusion - know which column you’re in.
