Шаблон:Convert/xx/AonSon
< Шаблон:Convert | xx
The Template:Convert/xx/AonSon formats a range where the 2 amounts are separated by "×" between the numbers, with adj=on.
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.
