Please enter a value

How to use

  1. Enter the amount in the "Value" box, e.g. 1.
  2. Pick the source unit from the "Unit" dropdown (bit/B/KB/…/PB).
  3. The result table shows both decimal (÷1000) and binary (÷1024) values.
  4. Tip: the two differ because vendors use 1000 while systems use 1024.

FAQ

Why are there two results, decimal and binary?

Vendors label 1KB=1000B (decimal) while OSes use 1KiB=1024B (binary), so the same value yields different results.

KB vs KiB?

KB usually means 1000 bytes; KiB is strictly 1024 bytes. This tool lists both for comparison.
