Abstract

The explicit use of the number `1' in the quotient-based expressions of units for intensive quantities involving counting together with a full description of the quantity being measured is recommended as an improvement on product-based expressions which omit the number 1 and do not fully explain the quantity presented. The benefits of these recommendations over proposals for new `units' as special names for one is also highlighted. In particular the nomenclature emphasises the dimensions of `one-ness' exhibited by the counting quantities and helps to provide a distinction between intensive and extensive quantities which would otherwise be lost, especially if the quantity being measured is not fully described.
