| 1 kJ = | 1000 J |
| 1 kcal = | 1000 cal |
| kcal / gram food: Carb | 4 kcal/1g |
| kcal/gram food: Fat (lipid) | 9 kcal/1g |
| kcal/gram food: Protein | 4 kcal/1g |
| Heat of Fusion for water | 80 cal/1g |
| Heat of Vaporization for water: | 540 cal/1g |
| 1 atm = | 760 mmHg = 760 torr |
| Boyles | P1V1=P2V2 |
