1 calorie = 4.18 J, but the "calorie" you see on food labels is actually a kilocalorie (kcal) or 1,000 true calories. Thus 1 "calorie" per nutrition labeling is actually 4,180 joules, or 4.18 kJ. How Are Heat and Temperature Related? You have seen how temperature relates to heat. ...
The energy in large/food calories E(Cal) is equal to the energy in joules E(J) divided by 4184:E(Cal) = E(J) / 4184ExampleConvert 600 joules to food calories.E(Cal) = 600J / 4184 = 0.1434 CalJoules to calories conversion calculator ►...

Converting units can be difficult, so when doing so it is important to remember to write down your computations step by step and to label all units. Joules (J) and calories, the derivative units of kilojoules (kJ) and kilocalories (kcal), are both used to measure energy. Keep in mind ...
Explain how to convert 243 calories to kilojoules. Explain how to convert 2.46 x 106 kJ to kcal. How many joules and kilocalories are equal to 0.691 kilojoules? Explain how to convert 1200 kilocalories to joules (in scientific notation). How many joules and kilojoules are equal to 0.119...
How do you convert 4 kilocalories to calories? Where do Celsius and Fahrenheit meet? How many sig figs is 0.0? How much heat in Joules must be removed to freeze 25 kg of water at 0 degrees C to produce 25 kg of ice? The formula for converting Celsius temperatures to Fahrenheit temperat...

If you took that 746 watts and ran it through an electric heater for an hour, it would produce 2,545 BTU (where a BTU is the amount of energy needed to raise the temperature of 1 pound of water 1 degree F). One BTU is equal to 1,055 joules, or 252 gram-calories or 0.252 food...
is given in joules / mol degree C, it's easiest to quote the mass of the substance in moles too. If the heat capacity is given in calories / kg degree C, your result will be in calories of heat instead of joules, which you can convert afterwards if you need the answer in joules....
