CALORIE (International Table) (cal/x). A unit of heat. One International Table calorie equals 4.1 S68 joules. (The 9th Conference Generale des Poids et Mesures adopted the joule as the unit of heat.)... 

By detinition, one calorie (International Table) is exactly 4.186 8 absolute joules which converts to 1.055 056 X 10 joules for one Btu (International Table). Also, by definition, one calorie (thermochemical) is exactly 4.184 absolute joules which converts to 1.054350 X 103 joules for one Btu (thermochemical). A mean calorie is TSOth of the heat required to raise the temperature of one gram of water at one atmosphere pressure from 0°C to 100°C and equals 4.19002 absolute joules. In all cases, the relationship between calorie and British thermal unit is established by 1 cal/(g. °C) = 1 Btu/(lb. 6SF). A mean Btu, therefore is 7So h of the heat required to raise the temperature of one pound of water at one atmosphere pressure from 32°F to 212°F and equals 1.055 87 X 103 joules. When values are given as Btu or calories, the type of unit (International Table, thermochemical, mean, or temperature of determination) should be given. In all cases for this table, conversions involving jou S are based on the absolute joule.

Practice (E 380) hsts five slightly different calories, all nearly equal to 4.185 J. In future, most of these will fade away, leaving only the calorie (International Table) equal to 4.186800 J. The term calorie is also used loosely, especially in the nutrition field, to mean 1000 calories, the kilocalorie, or large calorie . 

Calorie ka-b-re, lkal-re n [F calorie fr. L ca/orheat, fr. calere] (1866) (small calorie) A deprecated, small unit of heat energy the amount of heat required to raise the temperature of one gram of water, at or near 4°C, 1°C. The ASTM Standard for Metric Practice (E 380) lists five slightly different calories, all nearly equal to 4.185 J. In future, most of these will fade away, leaving only the calorie (International Table), equal to 4.186800 J. The term calorie is also used loosely, especially in the nutrition field, to mean 1,000 calories, the kilocalorie, or large calorie. ...
