A small gross [3] or a great hundred [4] refers to a group of 120 items (ten dozen, 10×12). The term can be abbreviated gr. or gro., and dates from the early 15th century. It derives from the Old French grosse douzaine, meaning "large dozen”. [5] The continued use of these terms in measurement and counting represents the duodecimal number ...
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.
Duodecimal system may refer to: duodecimal, a base-12 number system; Dewey Decimal Classification, ... additional terms may apply.
Also sometimes referred to as duodecimal hundred, although that could literally also mean 144, which is twelve squared; 144: a gross (a dozen dozens, second power of the duodecimal base), used mostly in commerce; 500: a ream, usually of paper. a monkey is a bet of £500 in British betting slang. 1000:
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
The current year represented in duodecimal (base 12) notation is written as 1206. Can anyone guess what the '6' at the end of the duodecimal representation of the current year stands for? 23.150.224.60 16:30, 8 September 2022 (UTC) It does not "stand for" anything. -- 27 is my favorite number.
The SI has special names for 22 of these coherent derived units (for example, hertz, the SI unit of measurement of frequency), but the rest merely reflect their derivation: for example, the square metre (m 2), the SI derived unit of area; and the kilogram per cubic metre (kg/m 3 or kg⋅m −3), the SI derived unit of density.
Some dodecahedra have the same combinatorial structure as the regular dodecahedron (in terms of the graph formed by its vertices and edges), but their pentagonal faces are not regular: The pyritohedron, a common crystal form in pyrite, has pyritohedral symmetry, while the tetartoid has tetrahedral symmetry.
