This is a documentationsubpage 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:

{{convert|37|–|162|cm|hand|2|abbr=in|lk=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 x-to-hands, hands-to-x, range-to-hands, or hands-to-range 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 one-tenth 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.
