Joule to Calories Calculator
Convert energy from Joules (J) to Calories (cal)
Converting Joules to Calories
To convert joules into calories, simply multiply the energy value by the conversion factor of 0.239006 calories per joule.
Since one joule corresponds to 0.239006 calories, the conversion formula is:
Conversion Formula
Example Calculation
Example:
- Energy = 5 joules
Calculation:
calories = (5 J × 0.239006) = 1.195029 cal
Understanding Joules and Calories
Each joule contains 0.239006 calories, which is why this factor is used in the conversion formula.
1 J = 0.239006 cal
Both joules and calories are units for measuring energy. Continue reading to learn more about these units.
What Is a Joule?
A joule is defined as the energy required to exert a force of one newton over a distance of one meter. It also represents the heat energy produced by a current of one ampere passing through a resistance of one ohm for one second.
Additionally, one joule is equivalent to the energy needed to move an electric charge of one coulomb through a potential difference of one volt, or one watt-second.
In the metric system, the joule is the standard unit of energy, abbreviated as J; for instance, 1 joule can be denoted as 1 J.
What Is a Calorie?
A calorie is defined as the amount of heat required to raise the temperature of one gram of water from 14.5 to 15.5 degrees Celsius.
In dietary contexts, the larger calorie, or kilocalorie, is often used, but it is commonly referred to simply as a “calorie.” When both terms are used together, the smaller calorie is typically called a “small calorie.”
Calories are abbreviated as cal; for example, 1 calorie can be expressed as 1 cal.
Practical Uses
Dietary Calculations
