Decimal vs Binary Prefixes
There are two standards for data size units:
- Decimal (SI) — 1 KB = 1,000 bytes, 1 MB = 1,000,000 bytes. Used by hard drive manufacturers and network bandwidth specs.
- Binary (IEC) — 1 KiB = 1,024 bytes, 1 MiB = 1,048,576 bytes. Used by operating systems (RAM, file sizes in Windows/Linux). This is why a 1 TB drive shows as ~931 GB in Windows.
