How to Use the Data Size Converter

1 Enter a value and select its unit (bits, bytes, KB, MB, GB, TB, PB).
2 See instant conversions to all other units.
3 Toggle between binary (1 KiB = 1024 bytes) and decimal (1 KB = 1000 bytes) systems.

The difference between binary and decimal units causes confusion: a 1 TB hard drive shows as ~931 GiB in your operating system because drives use decimal (1000) while OS uses binary (1024).

Binary prefixes (KiB, MiB, GiB) were standardized by IEC to eliminate ambiguity. This tool supports both systems for accurate conversions.
