A Calorie is not a unit of weight, it is a unit of energy used in nutrition. Nutritional Calories are called kilocalories by physical scientists, to distinguish them from the lowercased physical calorie when speaking. A calorie is the minimum amount of energy it takes to raise 1 gram of water by 1 degree Centigrade. A nutritional Calorie is 1000 times larger than a physical calorie. When people outside of science talk about 'calories', they usually mean nutritional Calories.
Einstein's Theory of Relativity implies that a substance heated by one Calorie will increase in mass by about 0.000000000000046 grams. In that sense, a Calorie does have an exact weight. However, that increase is negligible for the purposes of nutrition and weight management because Calories are stored in chemical compounds weighing much more than a Calorie.
The weight of substance that your body can convert into one Calorie depends on the substance and the chemical reactions it will undergo. A representative reaction is burning table sugar, which is similar to cellular respiration in energy yield. In this reaction, it takes about .372 grams of sugar to yield 1 Calorie of heat. The lipid molecules in fat cells have a considerably higher energy density, and will therefore weigh much less than .372 grams per calorie stored.
