Why Use ToolSnippet Data Storage & Byte Unit Converter?
Tips for Best Results
- IEC units (KiB, MiB, GiB) use powers of 1024 (2^10, 2^20, 2^30).
- SI units (KB, MB, GB) use powers of 1000 (10^3, 10^6, 10^9).
Frequently Asked Questions
What is the difference between GB and GiB?
A Gigabyte (GB) is decimal base-10 (10^9 = 1,000,000,000 bytes), whereas a Gibibyte (GiB) is binary base-2 (2^30 = 1,073,741,824 bytes).
Why does my 1 TB drive only show 931 GB in Windows?
Drive manufacturers advertise capacity in decimal TB (1,000,000,000,000 bytes), but Windows measures storage in binary TiB (1024^4), resulting in ~931.3 GiB of usable capacity.
