Convert between bytes, KB, MB, GB, and TB
Decimal: Used by hard drive manufacturers. Binary: Used by operating systems.
Decimal vs Binary
- Decimal (SI): 1 KB = 1,000 bytes, 1 MB = 1,000,000 bytes
- Binary (IEC): 1 KiB = 1,024 bytes, 1 MiB = 1,048,576 bytes
This is why a "500 GB" hard drive shows ~465 GB in your OS - manufacturers use decimal, but computers use binary.
