Solution

One calorie.
The calorie is defined as the amount of energy (heat) needed to increase the temperature of one gram of water by 1°C.

The SI energy unit is the joule. 1 Calorie = 4.186 joule.

A Calorie, or Cal , is equal to 1000 calories, and is sometimes called a kilocalorie, or kcal. 1 Cal = 1 kcal = 4184 J. The c.g.s. unit for energy is the erg. 1 erg = 1 g∙cm^2/s^2. ergs are a lot smaller than Joules; 10^7 ergs = 1 J.
