Where is this conversion used?

Data storage conversions are essential in computing, networking, and consumer electronics. Understanding the difference between bits and bytes, and between decimal prefixes (KB = 1,000 bytes) and binary prefixes (KiB = 1,024 bytes), prevents common confusion when comparing storage capacities. System administrators, software engineers, network architects, and consumer electronics buyers all need to convert between data units. Hard drive manufacturers use decimal prefixes (1 GB = 1,000,000,000 bytes), while operating systems often display binary values — which is why a "1 TB" drive might show as 931 GiB in Windows.

Internet speeds are measured in bits per second (Mbps), while file sizes are measured in bytes (MB). A 100 Mbps connection downloads approximately 12.5 MB per second.
