1 4⁄5 and 3 6⁄7 {{{u}}} The Template:Convert/and/AonSoff formats a range where the 2 amounts are separated with word "and" between the numbers. The range can text-wrap at "and" if the first amount > 4 long, such as a number in scientific x10 notation.
For unit-codes where the unit symbol is undefined (or blank), then the template also checks for literal "{{{u}}}" with leading curly brace "{" and then the unit name (depending on amount singular or plural) will be displayed instead.
