The thermochemical calorie was defined in 1930 by Frederick Rossini as 4.1833 joules. With the change to absolute electrical units in 1948, the thermochemical calorie was redefined to 4.184 joules, to keep the same quantity of energy represented by it
The National Bureau of Standards (NBS, now known as The National Institute of Standards and Technology) defined the cal15 as being the ammount of energy needed to warm 1g of water from 14.5°C to 15.5°C
