Conversion of units
editI was about to suggest an additional section with a matrix showing all the common units along the top and down the left hand side, with the relevant conversion factor in each of the cells, since I had already started such a chart in Template:Units of energy but unfortunately it has been deleted. Now I realise that all this information appears in Conversion of units#Energy, work, or heat. I'll add a link to that page for now, but still I wonder - would a conversion matrix of the common units be useful? LightYear 01:22, 12 July 2007 (UTC)
Relationship to Torque
editThe article claims that the similar units used for torque is "not a simple coincidence". I'd suggest that the explanation is in fact, an explanation of a coincidence - by applying a torque over 1 radian, by the definition of a radian, you happen to move through an arc equal in length to the distance from where the torque is being applied. Given that the torque is 1 newton metre, 1 radian will happen to cover the requisite distance to expend 1 newton-metre of work. Pretty coincidental I think! The important distinction is that in energy terms, the newton and the metre part of the unit are vectors in the same direction. In torque they are perpendicular (by convention only). The measurement is of something quite different. The fact that 1 radian will allow both units to be used in the same equation does not change the fact that the measurements are measuring a different phenomena, and the meaning of the "metre" part of the unit is quite different. I think this could be described better in the article. LightYear 04:51, 23 July 2007 (UTC)
Introduction
editMany sorts of units are used in energy discussions. They fall into two broad categories:
(a) those whose definition is not related to a particular fuel, which we here term "basic" units; and (b) those whose definition is related to idealized properties of a specific fuel, which we here term "source-based" units. These units, along with special topics related to electricity, are discussed in succeeding sections. Table 1 gives conversion factors between units, as well as the energy content of specific fuels. — Preceding unsigned comment added by Kambo Usuf (talk • contribs) 14:36, 18 October 2014 (UTC)
Units for the energy market
editThere are some units missing which are used quite often in the energy market. One could either make a new section just for energy market's units or add the links to the see also section.

- The BTU is in there. The others might be better suited to List of unusual units of measurement, which I have added to the See also section. Kendall-K1 (talk) 13:38, 24 August 2017 (UTC)
Units of power
editThere should be an equivalent article for units of power -- 65.92.246.142 (talk) 11:43, 4 January 2022 (UTC)
