 # Relation Between Calorie And Joule

Energy is the ability to do work. The energy can be measured using multiple units. Calorie and Joule are the units of energy. The relation between calorie and joule is proportionate. Which implies, any change in Calorie will change its equivalent value in Joules.

## Calorie And Joule

The relation between Calorie and Joule can be numerically written as-

 1 calorie = 4.2 joules 1 Calorie/kcal = 4.2 kilojoules.

Where,

• calorie is the unit of energy.
• Calorie or kilocalorie is the unit of energy = 1000 calorie.
• Joule is the unit of energy
• Kilojoule is the unit of energy, = 1000 joules.

Please note that calorie and Calorie are not the same. 1 Calorie = 1000 calories. Sometimes Calorie is often called as kilocalorie. Calorie and calorie both are the units of energy.

## Relationship Between Calorie And Joule

The relationship between calorie and joule are proportionate. Which implies, the calorie is directly proportional to the joule. That means-

• When the value in terms of calorie increases, its corresponding value in joules also increases at a rate of 4.2.
• When the value in terms of calorie decreases, its corresponding value in joules also decreases at a rate of 4.2.

Refer the table given below for definition, unit, and symbol of calorie and joule in physics and life science.

 Definition Symbol calorie The energy in the form of heat required to warm 1 kilogram of water by 10 C cal joule Work done (energy transferred) on an object when a force of 1N acts on it and moves it for a distance of 1 m in the direction of the force J

Here, 1 newton is written in short as 1N.

## Joule calorie conversion
