About:
bcal is a command-line utility for byte-level calculations and storage conversions. It allows users to perform arithmetic operations directly on human-readable storage units (KB, MB, GB, etc.) and convert between different units. The tool also functions as a calculator for expressions involving these units, making it highly practical for system administrators and developers.
Key Features:
  • Arithmetic operations on storage units (e.g., '2 GiB + 512 MiB')
  • Unit conversion between binary (IEC) and decimal (SI) standards
  • Byte address calculation and LBA/CHS conversion
  • Interactive mode with readline support
Use Cases:
  • Calculating required storage capacity for backups or virtual machines
  • Converting file sizes from one unit to another for documentation
  • Performing quick arithmetic on memory addresses or disk sectors
Alternatives:
  • calc – bcal is specialized for storage units, whereas calc is a general-purpose arbitrary precision calculator.
  • numconv – bcal offers a broader range of features including arithmetic and interactive mode, while numconv focuses strictly on number base conversion.
