Understanding Data Sizes
What are Data Size Units?
Data size units measure digital information storage and transfer. The base unit is the byte, with larger units built using powers of 1,024 (binary system) or 1,000 (decimal system).
This converter uses the binary system (1024-based), which is the standard in computer science and most accurate for digital storage calculations. This is how your operating system calculates storage space.
Binary System (IEC)
Used by operating systems and accurate for computer storage. Based on powers of 2 (2^10 = 1,024).
- • 1 KB = 1,024 Bytes
- • 1 MB = 1,024 KB
- • 1 GB = 1,024 MB
- • 1 TB = 1,024 GB
Decimal System (SI)
Used by manufacturers for marketing. Based on powers of 10 (10^3 = 1,000).
- • 1 KB = 1,000 Bytes
- • 1 MB = 1,000 KB
- • 1 GB = 1,000 MB
- • 1 TB = 1,000 GB
