Glossary » Units » Power (Heat Flow) » Watt
Watt (W) is a unit in the category of Power (Heat flow). It is also known as watts. This unit is commonly used in the SI unit system. Watt (W) has a dimension of ML2T-3 where M is mass, L is length, 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 Power (Heat flow) include Abwatt (emu of Power) (aW), British Thermal Unit (IT) Per Hour (Btu (IT)/h), British Thermal Unit (IT) Per Minute (Btu (IT)/min), British Thermal Unit (IT) Per Second (Btu (IT)/s), British Thermal Unit (therm.)
