HOW DOES THE CALORIE CONVERTER ON THEGYMGUIDES WORK?

  • Kilocalories to Joules 

A kilocalorie is equal to 4, 184 joules. To convert kcal to j, multiply the kcal by 4, 184 i.e. 1 kcal = 4, 184 J or 1 J = 0.00023900573614.  

  • Joules to Calories

Joules (J) refers to the energy transferred to an object by a one newton force applied to the object in the direction of its motion through a distance of one meter. A calorie (cal) refers to the amount of energy required to increase the temperature of one gram of water by one °C. This is however, referred to as the small calorie and doesn't when it comes to food. The large calorie (Cal), also referred to as the food calorie is equivalent to 1000 small calories. In labeling foods, the large calories are considered as kilocalories and is denoted as "C." Some foods are, however, labeled as kilocalories. 

To convert cal to j or j to Cal, simply multiply by cal by 4.184 since 1 cal (th) = 4.184 J or 1 J=0.2390057361. 

  • Kilocalorie to Calorie

A kilocalorie (kcal or Cal) is equal to 1000 calories or 4.1868 kilojoules. Kilocalories are usually considered large calories or Calories and are used to imply food items. In converting kcal to cal or cal to kcal, kcal is multiplied by 1000 cal. i.e. 1 kcal = 1000 cal or 1 cal= 0.001 kcal. 

  • Calories to Kilojoules 

Converting cal to kJ is done by multiplying the calorie value by 4.184. One kJ is equal to 0.239005736 calories. To convert kJ to calories, multiply the kilojoule value by 0.239005736 or divide by 4.184.   

  • Kilojoules to Kilocalories 

A kilojoule(kJ) is equal to 1000 joules while a kilocalorie (kcal/ Cal) is equal to 1000 calories or 4.1868 kilojoules. To convert kJ to kcal, the kcal is multiplied by 4.184 kJ i.e. 1 kJ = 0.2390057361 kcal or 1 kcal=4.184 kJ.
