Binary vs Decimal
There are two standards for measuring data storage:
| Standard | Base | 1 KB equals | Used by |
|---|---|---|---|
| Binary (IEC) | 1024 | 1,024 bytes | Operating systems, RAM |
| Decimal (SI) | 1000 | 1,000 bytes | Hard drives, SSDs, marketing |
Note: This is why a "1 TB" hard drive shows as ~931 GB in your operating system.
