Decimal vs. Binary Measurement
There are two systems for measuring data storage:
- Decimal (SI): Uses powers of 10 (1 KB = 1,000 Bytes). Used by hard drive manufacturers.
- Binary (IEC): Uses powers of 2 (1 KiB = 1,024 Bytes). Used internally by operating systems like Windows.
Frequently Asked Questions
Hard drive manufacturers use decimal measurement (1 TB = 1,000,000,000,000 bytes), while Windows uses binary measurement (1 TB = 1,099,511,627,776 bytes). The difference between these two systems causes the 931 GB display.
In decimal terms, 1 Terabyte equals 1,000 Gigabytes. In binary terms (TiB), 1 Terabyte equals 1,024 Gibibytes.
