The traditional way is to look it up in a reference book like the Chemical Rubber Company's Handbook of Chemistry and Physics (the "Rubber Bible" to generations of science students.) Today, go to Google and type in 1 joule in calories and the number you want will appear. Google understands the difference between a calorie and a Calorie, by the way! Of course, if you type in 6300 joules in Calories you get what you probably want, right off. Good Hunting!
