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.
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.
