This unit is commonly used in the SI unit system. Watt Per Square Meter (W/m2) has a dimension of MT-3 where M is mass, and T is time. This unit is the standard SI unit in this category.
Note that the seven base dimensions are M (Mass), L (Length), T (Time), Q (Temperature), N (Aamount of Substance), I (Electric Current), and J (Luminous Intensity).

Other units in the category of Energy flux include British Thermal Unit (IT) Per Hour Per Square Foot (Btu (IT)/h-ft2), British Thermal Unit (therm.) Per Hour Per Square Foot (Btu (therm.)/h-ft2), and Langley (flux) (ly).
