What is meant by calorie?
In simple words, the units of energies represent calories. In addition to this, there are 2 categories of calories which have been defined. While on one hand, there is gram or the small calorie & on the other hand, it is kilogram or large calorie. The symbol for small calorie is ‘cal’ & it means that it is the estimated amount of energy which is required in order to raise temperature of a gram of water by 1o Celsius that too at the pressure of 1 atmosphere.
However, the large calorie is represented by ‘Cal’ & it is also popular by the name food calorie. This is the reason that it is defined as kilogram. In addition to this, large calorie equals to 1, 000 small calories (1 kilocalorie or 1 kcal). As per the joule system, 1 small calorie equals to 4. 2 joules. It was Nicolas Clement who had 1st defined the word calorie to be a unit of heat energy way back in the year 1824. There have been other statements such as the one mentioned here & that is, the energy which is required to increase temperature of the given mass of water about 1o C & this depends on not only the atmospheric pressure but also the starting temperature.
