**Microgram Per Square Millimeter**

**Microgram Per Square Millimeter (µg/mm**is a unit in the category of

^{2})*Surface density*. It is also known as microgram/square millimeter. Microgram Per Square Millimeter (µg/mm

^{2}) has a dimension of ML

^{-2}where M is mass, and L is length. It essentially the same as the corresponding standard SI unit kg/m

^{2}.

Other units in the category of Surface density include Gram Per Square Centimeter (g/cm^{2}), Kilogram Per Square Centimeter (kg/cm^{2}), Kilogram Per Square Meter (kg/m^{2}), Ounce Mass Per Square Inch (ozm/in^{2}), Pound Mass Per Square Foot (lbm/ft^{2}), and Pound Mass Per Square Inch (lbm/in^{2}).
