Conversion basis

Decimal vs Binary data storage standards

The International System of Units (SI) defines 1 GB as 1,000 MB (decimal). Storage drive manufacturers use this standard.

Operating systems like Windows measure in binary powers of two where 1 GiB = 1,024 MiB. This tool shows accurate conversions for both formats.

Binary: GB = MB ÷ 1024 ; Decimal: GB = MB ÷ 1000
