## Joules to thermochemical calories

1 cal

_{th}= 4.184 JThe energy in thermochemical calories

E_{(calth)}is equal to the energy in joulesE_{(J)}divided by 4.184:

E_{(cal)}=E_{(J)}/ 4.184## Example

Convert 600 joules to thermochemical calories.

E_{(cal)}= 600J / 4.184 = 143.4 cal_{th}## Joules to 15ºC calories

1 cal

_{15}= 4.1855 JThe energy in 15ºC calories

E_{(cal15)}is equal to the energy in joulesE_{(J)}divided by 4.1855:

E_{(cal15)}=E_{(J)}/ 4.1855## Example

Convert 600 joules to 15ºC calories.

E_{(cal15)}= 600J / 4.1855 = 143.352 cal_{15}## Joules to large/food calories

1 Cal = 4.184 kJ = 4184 J

The energy in large/food calories

E_{(Cal)}is equal to the energy in joulesE_{(J)}divided by 4184:

E_{(Cal)}=E_{(J)}/ 4184## Example

Convert 600 joules to food calories.

E_{(Cal)}= 600J / 4184 = 0.1434 Cal
