మూస:Convert/to/AonSoff

1 ⁴⁄₅ to 3 ⁶⁄₇ {{{u}}}

The Template:Convert/to/AonSoff formats a range where the 2 amounts are separated with word "to" between the numbers. The range can text-wrap at "to" 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.
