What is this for#

Main purpose of this table, is to support making fast lookup convertions of hexadecimal numbers to decimal and opposite - decimal to hex.
Of course those conversions could be done very simply by any calculator which supports hex numbers (some included in calculla, but even the one included in Windows is enough). However, for some particular cases it is easier and faster to use lookup table (screen or printed).
That's why we made this: 4096 numbers ordered in very simple table.
Just to help you with hex↔dec conversions.

How to use this tool#

Take a look at the table:
  • each row contain 16 sequent decimal numbers
  • first row (upper heading) gives you last digit of HEX number (e.g. AA1)
  • first column (left heading) gives you starting digits of HEX number (e.g. AA1)
So, usage:
  • converting hex to decimal: get your hex (example: 2FA), find proper row (2fx) and column (xa), and you got the decimal result (762) at the intersection
  • converting decimal to hex: get your decimal number (example: 1221), find it in table - now, left heading gives you starting digits (4c), and top heading gives you last digit (5 - so your hexadecimal number is 4c5).

Ancient version of this site - links#

In December 2016 the Calculla website has been republished using new technologies and all calculators have been rewritten. Old version of the Calculla is still available through this link: v1.calculla.com. We left the version 1 of Calculla untouched for archival purposes.
