Hand (unit) divided by four, then the remainder is added after the radix point. Thus, a horse that measures 60 inches is 15 hands high (15 x 4 = 60) and a horse halfway between 15 and 16 hands is 15.2 hands, or 62 inches tall (15 x 4 + 2 = 62) Because the subdivision of a hand is a base 4 system, a horse 64 inches high is 16.0 hands high, not 15.4. A designation of "15.5 hands" is not halfway between 15 and 16 hands, but rather reads 15 hands and five inches, an impossibility in a base 4
Unit measure Unit measure Unit measure is an axiom of probability theory that states that the probability of the entire sample space is equal to one (unity); that is, "P"("S")=1 where "S" is the sample space. Loosely speaking, it means that "S" must be chosen so that when the experiment is performed, "something" happens. The term "measure" here refers to the measure-theoretic approach to probability. Violations of unit measure have been reported in arguments about the outcomes of events under which events acquire "probabilities" that are not the probabilities of probability theory. In situations such as these the term "probability" serves as
