What you should know about Joules and Calories

How many Calories are in one joule?

Thermochemical Calories
1 J = 0.23900573614 calth
15ºC calories
1 J = 0.23892008123 cal15
Large/food calories
1 J = 0.00023900573614 Cal

How many Joules are in one Calorie?

Thermochemical Calories
1 calth = 4.184 J
15ºC Calories
1 cal15 = 4.1855 J
Large/food Calories
1 Cal = 4184 J

Conversion Example:

If we want to convert 800J in calories, then we will proceed as following:
Joules to Thermochemical Calories
E(cal) = E(J) / 4.184 = 800 / 4.184 = 191.2 calth
Joules to 15ºC calories
E(cal15) = E(J) / 4.1855 = 800 / 4.1855 = 191.1 calth
Joules to Large/food calories
E(Cal) = E(J) / 4184 = 800 / 4184 = 0.1912 Cal
