About data storage units
Decimal (SI) prefixes multiply by 1,000: 1 GB = 1,000 MB. Binary (IEC) prefixes multiply by 1,024: 1 GiB = 1,024 MiB. Drive makers use decimal units, while some operating systems display binary values with decimal names, which explains why a new drive seems smaller than advertised.
Where data storage conversions are used
Storage conversions are used when comparing phone and cloud plans, buying drives and memory cards, estimating backup sizes and checking download sizes.
Conversion factors use exact international definitions where they exist (for example 1 inch = 2.54 cm and 1 lb = 0.45359237 kg). Results are rounded for display only.
