The thermochemical calorie was defined in 1930 by Frederick Rossini as 4.1833 joules. The change to absolute electrical units in 1948 involved redefining the thermochemical calorie as 4.184 joules (in order to keep the same quantity of energy represented by it). The thermochemical kilogram calorie is equal to 1,000 times that value - 4,184 J.
One Calorie (20°C) is the amount of energy needed to raise the temperature of 1 gram of air-free water from 19.5 to 20.5 °C at atmospheric pressure.
