Digital Storage: MB to GB
Digital file sizes often cause confusion because some systems use decimal units and others use binary units. This guide explains the difference so download and storage numbers are easier to read.
The formula
In decimal storage, 1 GB = 1000 MB. In binary storage, 1 GiB = 1024 MiB. Check which convention the source is using before comparing numbers.
Examples
| Input | Working | Result |
|---|---|---|
| 500 MB | 500 ÷ 1000 | 0.5 GB |
| 1500 MB | 1500 ÷ 1000 | 1.5 GB |
| 2048 MB | 2048 ÷ 1024 | 2 GiB |
| 10,000 MB | 10,000 ÷ 1000 | 10 GB |
Practical notes
- Phone storage, cloud plans and file download labels may use different unit conventions.
- MB and GB can mean different things depending on whether the source uses decimal or binary rules.
- For human-friendly comparisons, decimal units are often what marketing pages use.
- For operating system storage reports, binary units are very common.
FAQ
Why do the numbers sometimes seem inconsistent?
Because a “GB” from a storage box may use 1000 MB while an operating system may display binary values.
What should I trust?
Trust the unit convention used by the source you are comparing against and avoid mixing decimal and binary units in the same comparison.
