 BIPM - special names
The special names becquerel, gray, sievert and katal were specifically introduced because of the dangers to human health which might arise from mistakes involving the units reciprocal second, joule per kilogram and mole per second.
Thus the joule per kelvin (J/K) is the SI unit for the quantity heat capacity as well as for the quantity entropy; also the ampere (A) is the SI unit for the base quantity electric current as well as for the derived unit magnetomotive force.
Joule, for example, may formally be written newton metre, or even kilogram metre squared per second squared, but in a given situation some forms may be more helpful than others.

 The MSDS HyperGlossary: Energy Unit Conversions
The prefix "kilo" means 1,000, so one kJ = 1,000 J. As the energies associated with a single molecule or atom are quite small, we often find it easier to discuss the energy found in one mole of the substance, hence "per mole".

To avoid allusions to hypothetical moles of identical systems or to electrons not involved in the problem, and (more important) to enable mechanical calculations involving force, work, kinetic energy, and so forth to proceed without frequent unit conversions, this volume adheres to the joule as the unit of energy.
In synthesis, however, the designer usually wishes to understand how system properties will vary as controllable parameters are changed; for this, a graph can be more useful than a bare equation.

To express Celsius temperature, the unit ``degree Celsius'' which is equal to the unit ``kelvin'' is used; in this case, ``degree Celsius'' is a special name used in place of ``kelvin.'' An interval or difference of Celsius temperature can, however, be expressed in kelvins as well as in degrees Celsius.

The molar heat capacity, the amount of energy required to raise the temperature of one mole of a substance by one K (Kelvin), of silicon dioxide is 44 J/Kmol (J stands for Joule, a unit of energy, K is unit of temperature, mol stands for mole).
All this considered it is a valid and relatively small approximation, to say that Earth's crust is composed of 65% of silica and 35% Alumina, both by weight - basically we substitute the properties of Alumina for the minority of the remaining compounds and retain the value for silica.
Alumina, or aluminum oxide, its chemical formula is Al2O3, is the other most common mineral in Earth's crust, it is the component of a variety of minerals.

The units of energy and power advocated by Feynman for use at CalTech, the joule (J) and the watt (W), are metric (SI) units.
For example, the mass of carbon-12 is called 12 "atomic mass units" (u), because a mole of carbon-12 "weighs" 12 grams (or rather "has 12 grams of mass").
The mass of an atom, from a chemist's point of view, is given by the mass of a mole of these atoms.
