Data storage conversion tools

Storage units can use decimal multiples based on 1,000 or binary multiples based on 1,024. Drive manufacturers normally advertise decimal capacity, while some operating systems and technical tools display binary-style values. That difference explains why the same device can appear to have two different capacities.

Decimal versus binary

In decimal notation, 1 GB equals 1,000 MB. In binary notation, 1 GiB equals 1,024 MiB. Check which convention your software or provider uses before comparing storage plans, backup sizes, memory values, or transfer limits.
