What is calorie?
The calorie (cal) equals 4.184 joules. It was originally defined as the energy needed to raise one gram of water by one degree Celsius. Small calories are used in chemistry and physics.
What is joule?
The joule (J) is the SI unit of energy. It is defined as the work done by a force of one newton acting through a distance of one metre. Joules measure mechanical, electrical, and thermal energy.
How to convert cal to j
To convert Calorie to Joule, multiply the value by 4.184.
21940.73877 cal × 4.184 = 91800.051014 j
