Digital Storage Unit & Drive Size Converter
Convert data between Decimal (1,000-based) and Binary (1,024-based) storage units. Calculate exact Windows usable drive space for any SSD, HDD, or SD card.
Input Storage Value
Actual Space in Windows Explorer:
Windows labels binary Gibibytes (GiB) simply as "GB". A 1TB drive is exactly 1,000,000,000,000 bytes = 931.32 GiB.

Why Does Your 1TB SSD Only Show 931 GB in Windows?
Hard drive and flash memory manufacturers (Samsung, Crucial, Western Digital) follow the International System of Units (SI), where 1 KB = 1,000 Bytes and 1 TB = 1,000,000,000,000 Bytes.
However, computer operating systems like Microsoft Windows operate in binary architecture (powers of 2), where 1 KiB = 1,024 Bytes and 1 TiB = 1,099,511,627,776 Bytes. Windows calculates 1,000,000,000,000 ÷ (1024 × 1024 × 1024) = 931.32 GiB, but confusingly labels it with the decimal abbreviation "GB". Your drive is not missing storage!
