The relationship between calories and joule is proportionate. This implies that the calorie is directly proportional to the joule. That means-
When the value in terms of calories increases, its corresponding value in joule also increases at a rate of 4.2.
When the value in terms of calories decreases, its corresponding value in joule also decreases at a rate of 4.2.
Refer to the table given below for the 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 1 N 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 1 N.
Joule-Calorie conversion
In physics, the conversion between two units of energy, calorie to joule and joule to a calorie is crucial in solving problems. Scroll down the page for the list of values and their conversion from calorie to joule and joule to calorie.

Frequently Asked Questions – FAQs
Q1
What is heat?
With a body’s temperature increase, the molecules or atoms’ vibrations increase. These vibrations are then transferred from one part of the body to another. The measure of energy with which the molecules vibrate in a system is termed as heat stored in that object.Q2
What is Joule?
Joule is the SI unit of work or energy. One joule is defined as the amount of work done when a force of one newton acts on an object in the direction of its motion through a distance of one metre.Q3
What is the relation between power and energy?
The relation between power and energy is that power has energy units divided by time. The unit of power is Watts. Unit of energy is Joules. 1 Watt = 1 Joule/1 second.Q4
Can energy be stored?
Yes, energy can be stored. One efficient way to store energy is in the form of chemical energy in a battery. When connected to a circuit, energy stored in the battery is released to produce electricity. Energy can also be stored in many other ways. Batteries, gasoline, natural gas, food, water towers etc.Q5
Define one calorie of heat.
One calorie of heat is defined as the amount of heat needed to raise the temperature of one gram of water by one degree Celsius (or one kelvin). Test Your Knowledge On Relation Between Calorie And Joule!Q5
