This byte converter translates a value between bytes, KB, MB, GB and TB, in either binary (1024) or decimal (1000) base, showing every unit at once.
Make sense of storage sizes
Handy for comparing file sizes, RAM, bandwidth and disk capacity — and for understanding why a “1 TB” drive never shows a round terabyte. The conversion runs in your browser.
FAQ
What's the difference between base 1024 and 1000?
Base 1024 (binary) is what operating systems use, so 1 KB = 1024 bytes. Base 1000 (decimal) is what drive makers use, so 1 KB = 1000 bytes.
Why does my 1 TB drive show less space?
Drive makers label capacity in decimal (1 TB = 1,000,000,000,000 bytes), but your OS measures in binary, so it reads about 931 GB.
What about KiB, MiB and GiB?
Those are the strict binary units (1024-based). This tool's binary mode matches them, while decimal mode matches KB, MB, GB as drive makers use them.
