Convert between digital storage units — B, KB, MB, GB, TB, PB, EB. Supports both 1000 and 1024 bases.
What is the difference between base 1000 and base 1024?
This tool uses two conversion bases for the same units: base 1000 and base 1024. The unit labels remain B, KB, MB, GB, TB, PB, EB, but the numeric result changes with the selected base.
Why are there two systems?
Historically, computers used 1024 (2^10) for convenience. SI standards define prefixes as powers of 1000. This tool provides both bases for clarity.
How accurate is the conversion?
