Energy Unit Comparison能的单位比较
One of the difficulties of reading articles about energy resources is the plethora of units used. This is an attempt to give a comparison of some commonly quoted energy units. You may enter a number in any of the boxes to calculate the comparisons in other units.
The energy values for the common fuels are nominal values since the energy content of these fuels varies with the source.
The SI unit for energy is the Joule = newton x meter, the work done by exerting a newton of force through 1 meter of distance. In the CGS system, the energy unit is the erg = dyne x cm, the work done by exerting one dyne of force through 1 cm of distance. The Joule = 107 ergs. 能量的SI单位是焦耳=牛顿×米，即通过1米距离施加1牛顿的力所做的功。在CGS系统中，能量单位是尔格=达因×厘米，即通过1厘米距离施加1达因的力所做的功。焦耳=10⁷尔格。
阅读有关能源资源的文章之一困难在于使用的单位种类繁多。这是对一些常见能源单位的比较尝试。您可以在任意一个框中输入一个数值，以计算其他单位的比较结果。焦耳 x 10^ .....英尺-磅 x 10^ ..........卡路里 x 10^ ...............英热单位 x 10^ ....................千瓦时 x 10^ .........................汽油加仑 x 10^ ..............................1000立方英尺的天然气 x 10^ ...................................油桶 x 10^ ........................................吨煤 x 10^ 这些常见燃料的能源值是名义值，因为这些燃料的能量含量会因来源不同而有所变化。 中文译文中的待填/计算数值依次对应：1：j 2：jp 3：f 4：fp 5：c 6：cp 7：b 8：bp 9：k 10：kp 11：g 12：gp 13：n 14：np 15：o 16：op 17：t 18：tp。实际数值以上方原输入框为准。 |
