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 ...

Food Calories Every activity in which you engage, whether it’s napping, doing housework or running a marathon, requires energy. Between the extremes of resting and hard exercise, the human body expends roughly 100 to 1,000 watts of power continually -- all of it coming from food. The sug...
For example, energy can be expressed in joules, British thermal units (BTUs), calories and kilowatt hours.Answer and Explanation: Become a Study.com member to unlock this answer! Create your account View this answer The first step in converting joules to BTU is to research the conversion ...
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....
You are seeking to heat 200 ml of water for your morning cup of coffee from 20 degrees C to 100 degrees C. How much heat is required in joules? How would you calculate the volume, in cubic centimeters, of 86 mass ounces of copper (density = 8.98 g/mL). What is the caloric value...
Now, in this context, heat is sometimes referred to as heat energy, and it's the total energy contained within a substance. Energy is simply the ability to do work. Heat energy, along with other forms of energy, is measured in joules (J) or calories (cal). Temperature is the aver...
Divide by the number of cubic centimeters in a gallon, 3,785.4, to find the high value of 9,145.7 calories per cubic centimeter. Calculate low calorific values. Diesel No. 2's low calorific value is 128,450 Btu per gallon. Plugging in the same conversion factors, the low value is 252...
One BTU is equal to 1,055 joules, or 252 gram-calories or 0.252 food calories. Presumably, a horse producing 1 horsepower would burn 641 Calories in one hour if it were 100 percent efficient. Some countries use a similar but distinct unit of power measurement known as the metric horsepower...
