🧠Why two bases?
Storage makers use SI (1 KB = 1000 bytes) while operating systems usually show binary (1 KiB = 1024 bytes) — that's why your "1 TB" drive reads as ~931 GiB. Toggle the base above to see both.

4. The All units, live panel shows your value in every unit at once — perfect for quick sanity checks.
