Units, such as the joule, newton, volt and ohm, are SI units, but they are not base SI units. Dimensional analysis: The main idea of “deriving” a derived unit is to treat units like algebraic terms, and manipulate them accordingly to get the right derived unit for the quantity. (See...

We propose that gas and water flux densities should be expressed in terms of kg m -2 s -1 and heat flux densities in terms of W m -2. The joule per kilogram (J/kg) is suggested as the preferred unit for describing water potential, and hydraulic conductivity then has units of kg s...
TheSIsystem therefore takes the ampere as one of its fundamental units. 因此,SI制取安培作为它的基本单位之一. 辞典例句 The unit of work and energy in theSIsystem is the joule ( J ). 在国际单位制(SI)中,功和能的单位是焦耳 ( J ). ...
