Byte Size Converter
Converts between decimal units (KB, MB, GB — powers of 1000) and binary units (KiB, MiB, GiB — powers of 1024), shows the exact byte count, and explains why a "500 GB" drive shows up as 465 "GB" in your OS.

Notes
- Storage vendors use decimal units; Windows displays binary units but labels them KB/MB/GB — the two drift apart by 2.4% per thousand-step.
- RAM is always binary; network bandwidth is always decimal bits per second.
