It is also worth noting that James Watt advocated a universal decimal-based system of measurement - see pages 59/60 of this book: http://www.freeinfosociety.com/media/pdf/4750.pdf

Thanks for the report. Please notice your error in the spelling of SI unit names (James is Watt, the unit is watt). Concerning the unification topic, James Watt had suggested it centuries ago with the introduction of his horsepower. That unit did not, of course, fit a coherent system of units and also became corrupt by being assigned several different values. It should have been discarded the moment Si was born. The power generating people, being smarter than the power consuming people, did standardize on the watt. The others did not, except for a few cases, like light bulbs. Now the piddle power generating people in the renewable energy field are blocking the watt for generation so that ordinary people cannot make comparisons easily. The use "much better" (for their purpose) units as an "average house" and similar "flexible" terms. I am pessimistic about a breakthrough in the universal watt usage, despite article.

The international standards bodies are obsoleting all units but the watt. http://www.apcmedia.com/salestools/NRAN-5TE6HE/NRAN-5TE6HE_R3_EN.pdf Heat is energy and is commonly expressed in Joules, BTU, Tons, or Calories. Common measures of heat output rate for equipment are BTU per hour, Tons per day, and Joules per second (Joules per second is equal to Watts). There is no compelling reason why all of these different measures are used to express the same commodities, yet any and all of them might be used to express power or cooling capacities. The mixed use of these measures causes a great deal of senseless confusion for users and specifiers. Fortunately, there is a worldwide trend among standard-setting organizations to move all power and cooling capacity measurements to a common standard, the Watt. The archaic terms of BTU and Tons will be phased out over time. 1 For this reason, this paper will discuss cooling and power capacities in Watts. The use of the Watt as the common standard is fortuitous, because it simplifies the work associated with data center design as will be explained later.
