The Misalian decadozenal system is a system for using base 120 in English created by jan Misali. While his seximal (base 6) system is still his favorite, nevertheless, he argues in favor of base 120 using similar arguments.[1]

It is a mixed-radix system, employing a combination of bases 10 and 12. The digits for 10 and 11 are X and E, already in common use by base 12 proponents. The maximal digits in each position are as follows:

    ...9E9E9E.E9E9E9... 

Naming numbers

  • 12 (10120) is "dozen".
  • 120 (100120) is "twelfty".
  • 14400 (1 0000120) has been left unnamed, though a variant suggested is "gross hundred".
