Byte Units Guide
Byte units measure digital storage capacity. There are two standards: decimal (SI) using powers of 1000 (KB, MB, GB) and binary (IEC) using powers of 1024 (KiB, MiB, GiB).
Hard drive manufacturers use decimal units, while RAM and operating systems typically use binary. This discrepancy explains why a "500 GB" drive shows as approximately "465 GiB" in your operating system.
