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
Facial width to height ratio Facial width to height ratio Facial width to height ratio (fWHR) is a measure derived from archaeological skull measurements. fWHR is not linked with adolescent testosterone, and has been proposed as: a predictor of aggression, cause of death by violence, and also with CEO success probability. While most studies have found some significance some have found little correlation. fWHR has also been used in primate studies with similar findings. Width is measured as upper bizygomatic width (the widest central bit of the face), height measurement used is upper facial height, from the top of the eyelids (approximately the nasion) to
