Binary vs Decimal

Unit	Binary (IEC)	Decimal (SI)
Kilobyte (KB)	1,024 bytes (KiB)	1,000 bytes
Megabyte (MB)	1,048,576 bytes (MiB)	1,000,000 bytes
Gigabyte (GB)	1,073,741,824 bytes (GiB)	1,000,000,000 bytes

📌 OS (Windows/Linux/macOS) reports storage in binary. Hard drive manufacturers use decimal, which is why a "1 TB" drive shows as ~931 GiB in your OS.

Frequently Asked Questions

Manufacturers use decimal (1 TB = 10¹² bytes), but your OS uses binary (1 GiB = 2³⁰ bytes). 10¹² ÷ 2³⁰ ≈ 931 GiB. The drive is full size — it's just different counting systems.

MB (megabyte) in the decimal system = 1,000,000 bytes. MiB (mebibyte) in binary = 1,048,576 bytes. The ~4.9% difference becomes significant at larger sizes.
