About the Byte Converter

Storage units come in two flavours: decimal (1 GB = 1,000 MB) used by drive manufacturers, and binary (1 GiB = 1,024 MiB) used by operating systems. That is why a "1 TB" drive shows up as about 931 GiB. Both sets are included here so you can compare them directly.

Also known as: digital storage unit converter, digital storage conversion, data size converter, bytes to gigabytes, storage unit converter, kb mb gb tb.
