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
Link (unit) known remaining application of the link is in the service of some surveying in the United States, which relates then to the definition of the survey foot. During most of its useful life, a modern degree of precision in the link's measure was neither expected nor possible. For historical purpose, though, we can establish three highly accurate conversions to SI equivalents. Link (unit) The link (usually abbreviated as "l.", "li." or "lnk."), sometimes called a Gunter’s link, is a unit of length formerly used in many English-speaking countries. A link is exactly of a foot, or exactly 7.92 inches or
