This is a documentation subpage for Template:Convert/hand (see that page for the template itself). It contains usage information, categories, and other content that are not part of the original template page. 
The Template:Convert/hand converts hands of horse height, such as with inches, meters or cm. The conversion is 1 hand = 4 inches.^{[1]} A fraction indicates inches, so "13.2" denotes 13 + 1/2 hands, rather than 2/10 or 1/5 hand. Examples:

 {{convert57inhand}} → 57 inches (14.1 h)
 {{convert2mhand}} → 2 meters (19.3 h)
 {{convert9.1handin}} → 9.1 hands (37 in)
 {{convert14.1handin}} → 14.1 hands (57 in)
 {{convert14.1handcm}} → 14.1 hands (145 cm)
 {{convert14.1handin cm}} → 14.1 hands (57 in; 145 cm)
 {{convert14.114.6handcm}} → 14.1–14.6 hands (145–157 cm)
 {{convert5057inhand}} → 50–57 inches (12.2–14.1 h)
 {{convert23mhand}} → 2–3 meters (19.3–29.2 h)
 {{convert57or59inhandabbr=on}} → 57 or 59 in (14.1 or 14.3 h)
 {{convert137139cmhandlk=on}} → 137–139 centimeters (13.2–13.3 h)
 {{convert37–162cmhand2abbr=inlk=out}} → 37–162 cm (3.26–15.38 hands)
Unlike most Convert subtemplates, Convert/hand has 4 sections of special calculations to transform amounts in "hands.inches" notation, for xtohands, handstox, rangetohands, or handstorange of other units. The logic changes any fractional hands into decimals .1, .2 or .3 by checking parameter 2 to have "(" using {{padleft:1(62) }} then resetting parameter 2, with the fraction multiplied by 100 & divided by 250, as onetenth the multiple of 25. This is the first Convert subtemplate to calculate numbers which are not in decimal format (where ".1" is ^{1}⁄_{4} not ^{1}⁄_{10}), as would be a complex format also for hexadecimal or binary numbers.
