The SI unit of heat and energy is the joule (J). One joule is the equivalent of 0.2390 calories, or one calorie equals 4.184 joules. Table 16-1 shows the relationships among calories, nutritional Calories, joules, and kilojoules (kJ) and the conversion factors you can use to convert from one unit to another. 

Table 15.1 summarizes the relationships between calories, nutritional Calories, joules, and kilojoules (kj) and the conversion factors you can use to convert from one unit to another. 

Affinity The quantitative expression of substantivity. It is the difference between the chemical potential of the dye in its standard state in the fibre and the corresponding potential in the dyebath. Note Affinity is usually expressed in units of calories (joules) per mole. Use of this term in a qualitative sense, synonymous with substantivity, is frowned on. 

The SI Systeme International d Unites) unit of energy is the joule (J) An older unit is the calorie (cal) Most or game chemists still express energy changes in units of kilocalories per mole (1 kcal/mol = 4 184 kJ/mol)... 

At one time or another, all of us have tangled with problems of units, but generally these decrease in severity and frequency with experience. Advanced students juggle kilograms and grams, centimeters and angstroms, joules and calories, and rarely fumble in the process. Electrical units are sometimes more troublesome.
