在国际单位制中,功、能和热量的国际制单位(SI 单位)都是焦耳,它是一个很重要的导出单位。这一个单位可以取代所有其它功、能和热量的单位,包括常用的米制、英制和制外单位约有20多种。按国际计量大会的建议,除电子伏特可以与焦耳并用外,其它一般都应取缔。尤其明确指出,在化学和分子物理学中广泛使用的各种卡应全部改为焦耳。目前,有些国家已 In the international system of units, the international units of work, energy and heat (SI units) are joules, which is a very important export unit. This unit can replace about 20 other kinds of energy, heat and energy units, including the usual metric, imperial and extra-territorial units. According to the recommendations of the International Conference on Measurement, in addition to the use of electronic volt and joule, the other should generally be banned. In particular, it is clear that the various cards widely used in chemistry and molecular physics should all be replaced by joules. At present, some countries have already
