Normally you just enter 1 in the "Convert What?" field and that gives you the conversion factor.
1 calorie [I.T.] = 0.0041868 kilojoule
Now you have a conversion factor, just multiply it by the calories to get kilojoules.
6500 * 0.0041868 = 27.2142 kilojoule
That is what I think you were asking.
A calorie (was) defined as the amount of energy required to raise the temperature of 1 gram of water by 1 degree celsius at a pressure of 1 atmosphere. That is why you see "calorie [15º]", which defines what temperature range the calorie was measured at, since it is different for every temperature.
A more common calorie is the International Steam Table calorie, or I.T. for short, which was standardized in 1956. It is defined to be exactly 4.1868 joules.
