What is the specic heat of water ?

via Google :

The SI unit of specific heat capacity is joule per kelvin per kilogram, J⋅kg−1⋅K−1. For example, the heat required to raise the temperature of 1 kg of water by 1 K is 4184 joules so the specific heat capacity of water is 4184 J⋅kg−1⋅K−1.

or, in calories:

The specific heat of water is 1 calorie/gram °C = 4.186 joule/gram °C
