Sales per unit area
In retail, sales per unit area is a standard and usually the primary measurement of store success. The unit of area is usually square metres in the metric system or square feet in U.S. customary units. Square feet are also widely used in retailing in the United Kingdom, but there are signs of a trend towards use of square meters.
