The duodecimal system, also known as base twelve or dozenal, is a positional numeral system using twelve as its base. In duodecimal, the number twelve is denoted "10", meaning 1 twelve and 0 units; in the decimal system, this number is instead written as "12" meaning 1 ten and 2 units, and the string "10" means ten.

The dozenal system (also known as base-dozen) is positional notation numeral system using dozen as its base. In dozenal, the number ten (also known as dek ) may be written as "A", "X", "T" or a rotated "2" (introduced by Sir Isaac Pitman); the number eleven (also known as el , elv, lev, or ven) may be written as "B", "E", or a rotated "3" (also ...

The Dozenal Society of America is an international non-profit dedicated to researching, using, and teaching about dozenals (duodecimals) and other non-decimal number bases.

The duodecimal (also known as base-12 or dozenal) system is a numeral system using twelve as its base. The number ten may be written as A, the number eleven as B, and the number twelve as 10. The number 12 has six factors, which are 1, 2, 3, 4, 6, and 12.

The dozenal system makes fractions easier. One-third is a common fraction, but when it is converted to decimal it becomes 0.333 … and the threes repeat forever. In dozenal, one-third is simply 0.4. (Note that that is four-dozenths, not four-tenths.) One-quarter is 0.3 in the dozenal system, neater than 0.25 in decimal.

The dozenal system (also known as base 12, duodecimal, uncial, or unnilial or unqual in Systematic Dozenal Nomenclature) is a positional notation with a radix of 12. It uses a set of 12 digits. Due to its high divisibility, dozenal has been frequently proposed as an …

Numbers based on 12 digits. (But some people use other symbols instead of A and B, such as an upside-down 2 and 3.) Also called "dozenal", because 12 is a dozen. Below is a dozenal multiplication table: Illustrated definition of Duodecimal: Numbers based on 12 digits. The digits are: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A and B.

This is the fully-fleshed out, definitive work on Systematic Dozenal Nomenclature, a powerful and robust way of speaking about and using dozenal numbers. Described in several parts in the DSA's Newscast in 11E9, the system was described briefly in this article in The Duodecimal Bulletin WN X0, followed by the full exposition in this article ...

Duodecimal (or dozenal) is a counting system based on the number 12, and it has some advantages over the base-10 decimal method of counting. One of them is a lower abundance of repeating decimals for simpler fractions; another is the high divisibility of 12.

The DSGB, The Dozenal Society of Great Britain (founded 1959) and the DSA, The Dozenal Society of America (founded 1944) are separate organisations with a common aim: to draw attention to the advantages of the Dozen (or twelve-based) system for numeration and measurement. We consider that the decimal system is inadequate and of limited ...
