MB to GB: real-world reference points
Most confusion here is not conversion but which base the number was written in.
- 1 GB as sold (decimal) 1,000 MB
- 1 GiB as shown by Windows 1,024 MiB
- 25 MB email attachment limit 0.025 GB
- 700 MB CD 0.7 GB
Note: Storage is sold in decimal units (1 GB = 1,000 MB) while most operating systems report binary units (1 GiB = 1,024 MiB). That base difference, not a faulty drive, is why a 500 GB disk shows about 465 GB.
