About Data Storage

Digital storage is measured in bits and bytes. This converter uses binary prefixes (powers of 1024), matching how operating systems report file sizes.

Note: Drive manufacturers use decimal prefixes (powers of 1000), so a "1 TB" drive shows ~931 GiB in Windows.

Quick Reference

Unit	= Bytes
1 KB	1,024
1 MB	1,048,576
1 GB	1,073,741,824
1 TB	1,099,511,627,776

Pro Tips

Internet speeds are measured in bits per second (Mbps), while file sizes use bytes — divide Mbps by 8 to get MB/s download speed.

A typical HD movie is around 4–8 GB; a 4K Blu-ray can exceed 100 GB.
