1 joule is 0,239 calories. so 515 x 0,239 = 123,085 calories
Ha. I think you mean kilojoules, which would be 1000.

Q (heat) = mass*Specific Heat*Temperature differenceI assume 2.5 * 101 Joules? or 25 J & 10 grams of substance?25 J = 10 grams * (SH) * (70-10oC)25 J =10 g *60oC * SHSH = 25 J/(10 g * 60oC)S.H. = 0.0417 J/gOC
m stands for massE is energy, m is mass, and c is the speed of light.The formula shows what the energy equivalent of matter is: the energy obtained by changing a gram of mass to energy is 25 million kilowatt hours or 9 x 1013 joules.
There are 704 calories in 704 calories. If you intended to ask about joules, then 704 calories is about 2,947.51 joules.
75.2 calories equates to about 314.85 joules. (about 4.1868 joules per calorie).
148 calories is 619.6 joules. Since one calorie = 4.18 joules then you multiply that number by 148 and you get 618.64 joules (619 rounded)
4.18400 joules = 1 calorie, so 12.552 joules = 3 calories
15 joules is 3.5826884 calories.
1,850 calories is 7740.4 Joules.
To convert calories to joules, multiply by 4.184. So, 5.42 calories is equal to 22.68448 joules.
162 calories is 678.2616 joules. For most purposes you don't need such accuracy, remember one calorie = 4.2 Joules. This is called the mechanical equivalent of heat, and is a useful number to memorize.
There are approximately 155 calories in 650 joules. One calorie is equivalent to about 4.184 joules.
1 calorie = 4.1858 joules 1 joule = 0.2389029576186153 calories As an example, convert 5 calories to joules. 1 calorie = 4.1858 joules, therefore 5 calories = 4.1858 x 5 joules = 20.929 joules. So when converting calories to joules, multiply the number of calories by 4.1858 to give you the number of joules.
There are approximately 231 joules in 55.2 calories.
2800 joules is 669.2 calories.
