ByteSize

This library makes byte quantities easier to work with by giving them a clear, unambiguous representation in code.

Supports both decimal (SI) and binary (IEC) units (See this).

Decimal: 1 kilobyte (KB) equals 1,000 bytes. Supported units include KB, MB, GB, TB, and PB.
Binary: 1 kibibyte (KiB) equals 1,024 bytes. Supported units include KiB, MiB, GiB, TiB, and PiB.

It handles conversions and provides methods for creating and retrieving values for any of those units.
