| In scientific terms, 1 calorie is a kilocalorie, which is the amount of energy required to raise 1 gram of water 1 degree Celsius. |
|
| One kilocalorie is the amount of heat energy required to raise one kilogram of water from 14.5 to 15.5 °C at one atmosphere of pressure. |
|
| In the case of maize-based ethanol, for example, 1.3 kilocalories of oil are needed to produce 1 kilocalorie of bioethanol. |
|
| This allows you to obtain precise kilocalorie calculations when the nutritional plan is given out. |
|
| One kilocalorie is equivalent to 4.184 kilojoules. |
|
| Note that general food rations are not individualized. Thus, if there is a high prevalence of HIV but individual status is not known, all food rations for all families would have a higher kilocalorie amount. |
