What is the difference between binary and decimal?

Binary (KiB, MiB) uses base 1024: 1 KiB = 1024 bytes. Decimal (KB, MB) uses base 1000: 1 KB = 1000 bytes. RAM and SSDs use binary; hard drive manufacturers traditionally use decimal.

Why does my 1 TB hard drive show as 931 GB?

Hard drives use decimal (1000-based) capacity labeling, while Windows often displays sizes in binary (1024-based). 1,000,000,000,000 bytes ÷ 1,073,741,824 bytes/GiB ≈ 931 GiB.

Which mode should I use?

Use binary for RAM, SSDs, and USB drives. Use decimal for comparing manufacturer specifications of hard drives and external storage.

What are the exact conversion factors?

Binary: 1 KB=1024 B, 1 MB=1024² B, 1 GB=1024³ B. Decimal: 1 KB=1000 B, 1 MB=1000² B, 1 GB=1000³ B.
