About File size converter

Convert between decimal storage units and binary storage units using exact integer arithmetic internally. Large byte counts do not pass through floating-point numbers.

Steps, and limitations

How to use it

  1. Enter a nonnegative size and select its source unit.
  2. Compare the decimal and binary unit results.
  3. Copy the conversion table.

Things to know

  • Decimal units use powers of 1000; binary units use powers of 1024. A byte contains eight bits, but this tool reports bytes, not network bit rates.
  • Fractional results are rounded for display to eight decimal places; the input supports up to eight fractional digits.
