Before you use the result

B to GB context and checks

Best use
Use data-storage conversions for file sizes, drive capacity, backups, memory cards, and software download estimates.
Common mistake
Decimal and binary prefixes can differ. GB, GiB, MB, and MiB may not mean the same thing in hardware labels and operating systems.
Precision note
Keep the original value and prefix convention when comparing storage, because rounding can hide meaningful capacity differences.

Example check: 1 B converts to 1e-9 GB. Use this known value to sanity-check a spreadsheet, homework solution, spec sheet, or manual calculation.
