Calories to Kilojoules Converter
Energy Conversion - Convert Calorie to Joule (kcal to joule) or Joule to Calorie (j to kcal)
How to Convert Calories to Joules and Joules to Calories
- To convert Calories to Joules (kJ)/Energy, multiply given Calorie value by 4.184
kJ = 4.184 * kcal
For example, 3500 Calories = 3500 x 4.184 = 14,644.0 kiloJoules - To convert Energy or Joules to Calorie, divide by 4.184
kcal = kJ / 4.184
For Example, to find out how much calories are in 1500 Joules of energy, kcal = 1500/4.184 = 358.5 kcal
Converting Calories to Energy
This section shows relation between cal, kcal, joule and kJoule. Both cal and joule are units of energy.
Remember, a kilo calorie (kcal) is 1000 times of calories (small c)
A kilo calorie is same as Calorie (capital C)
A kilo Joule (kJ) is 1000 joules
kcal to kjoules (kcal to kj)
1 kcal = 4.184 kj
kcal to joules (kcal to j)
1 kcal = 4184 joules
cal to joule ( cal to j)
1 cal = 4184 joules
cal to kjoule (cal to kj)
1 cal = 4.184 kjoules
kjoules to kilo calories (kj to kcal)
1 kj = 0.239 kcal
kjoules to cal ( kj to cal, kj to gram calorie)
1 kj = 239 cal
joule to kcal (J to kcal)
1 j = 0.00239 kcal
joules to calories (J to calories)
1 j = 0.24 kcal
What are Kilo joules and Calories?
- A Joule is a SI unit of energy and is defined as the force on an object to move it by 1 meter with 1 newton force
- A Kilo Joule, abbreviated as kJ, is equal to 1000 times joule (1 kJ = 1000 joules)
- A calorie is also unit of energy but it is not the SI unit. It is defined as the amount of energy needed to raise the temperature of 1 gm of water by 1 degree Celsius.
- A Food Calorie is the energy contained in food. It is measured in terms of kilo calories (1000 cal)
- One Calorie (kcal) is equal to 4.184 kilojoules.
Why do we need Calorie to Joules Converter?
- While both Joule and Calorie are units of energy, Joule is the International Standard. However, Calories continues to be the preferred unit in certain areas such as Food/Nutrition, Heat and Chemical Processes.
- The usage also varies between different countries. Some countries use only Joule as the standard measure of energy. Other countries use a mix of both depending on the application.
- The Calorie-Joule conversion tools are needed for ensuring compatability between various applications and groups that use these energy units interchangeably. Nutritionists/Medical Professionals prefer to use Calories whereas Physicists/Scientists use Joules.
- The calorie to joule conversion is used in a variety of applications, including:
- Food Energy : It is the energy contained in food and drinks. Calories are still the most preferred and widely used unit to specify the same. For eg, The energy released from 1 gram of fat is equal to about 9 calories, energy released by 1 gram of protein or carbs is 4 calories.
- The energy required to perform an activity such as swimming, weight lifting, running, climbing is expressed in Calories or KJ depending on the country. For eg, swimming uses 20-40 kJ / min or 4.5-9.5 kal / min
- When it comes to energy measurements in other areas, Joules is used along with a corresponding preferred unit such as kWh, btu, hp, eV, Newton-meter specific to the type such as Electrical Energy, Mechanical Energy, Thermal Energy, Gravitational Energy, Solar Energy, Chemical Energy, and so on...

FAQ on Calorie to Joules and Joules to Calories Calculator
As per standard definition, it is the amount of energy required to raise the temperature of 1 gram (ml) of water by 1 degree Celsius.
This is also called as the 'thermochemical calorie'. 1 calorie = 4.184 Joule.
1 Kilocalorie (C) = 4.184 Kjoule
It is the System International Unit (SI) unit of energy and named after Joule.
To raise the temperature of 1 g of water by 1 degree celsius needs almost 4000 Joules of energy.
It is measured by taking the difference in temperature divided by mass of water.
Both are units of energy. The system international unit of energy is Joule.
Energy is defined as the ability to do work. The only difference is the value they represent for measuring energy.
1 Calorie (kcal) = 4.184 kilo joules. The Big 'C' in Calorie is same as kilo calorie.
1 kilo calorie (kcal) = 1000 calories. 1 C (capital C) = 1000 calories = 1 kcal.
calorie is bigger than joule. 4.18 joules make 1 calorie. (thermochemical calorie). 1 Calorie (kcal)= 4184 joules
All Nutritional calories are in Kilo calories. All food items and beverages use Kilocalorie by default and specify it as 'Calorie' with a Capital 'C'.
Diet / Nutrition Calorie are all Kilocalories (1000 calorie).
Calories 100 in food items means 100 kilo calories. 1 C = 1000 calories = 4.148 kJoules
If we assume a cup is 250 ml capacity. To raise 1 ml by 1 degree takes 1 calorie of energy.
To raise 250 ml by 1 degree will take 250 calories.
To raise 250ml by 70 degrees (30 degree to 100 degree) will need 17500 calories or 84700kJ.
1 kcal = 1000 calories = 0.129598 kg. 1 kg = 7700 calories.
This measure is called BMR and it is the energy requirement (in terms of calories) at rest to maintain basic functions of the body.
The average BMR is about 1409 kcal (5900 kJ) for a woman and about 1696 kcal (7100 kJ) for a man.See BMR for more details.
Nutrition calorie is 1000 times the thermochemical calorie and indicated by 'C' . 1 C = 1000 cal = 1 Kilocal = 4.184 kJoules
1000 calories in 1 food/nutrition calorie
100000 calories
140 Calories (kcal) = 140000 cal (thermal cal) . 0 Calories in diet coke
