Duodecimal
Base-12 numeral system

A duodecimal system, also known as base twelve or dozenal, is a positional numeral system using twelve as its base.

In duodecimal, "100" means twelve squared (144), "1,000" means twelve cubed (1,728), and "0.1" means one twelfth (0.08333...).
This brief starts where responsible research should: with the source description of “Duodecimal” as base-12 numeral system. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as base-12 numeral system. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 13, 2026.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
