Template:Convert/list of units/item

The Template:Convert/list of units/item processes one unit-code to display within the tables of the documentation page Convert/list_of_units for Template:Convert. The parameters are:
 * T - the unit code
 * note - a text note to display in the table
 * rowspan - the number of table rows the unit will span
 * altab - the altab
 * us - the spelling for a U.S. variation
 * fmt - beginning markup to format the conversion factor
 * fmtend - ending markup to format the conversion factor
 * d - (internal) template name to format data as a table row

This template invokes a typical conversion of a unit, but rather than converting to another unit, it triggers the display of the internal data used to calculate the specified conversion.
