joules to calories converterAbout These Units
calories (cal)
The calorie (lowercase c) was originally defined as the heat required to raise 1 gram of water by 1°C. It is a tiny unit, often called the 'gram calorie'. It is mostly used in chemistry and physics today, not for food.
Heating 1 gram of water by 1°C takes 1 calorie.
Commonly used in: Chemistry experiments, Thermodynamics, Specific heat capacity, Physics problems.
joules (J)
The Joule (J) is the standard unit of energy in the International System of Units (SI). It is named after James Prescott Joule, who proved that heat is a form of energy. One Joule is the work done by a force of one Newton moving an object one meter. It is a small unit: lifting a small apple one meter takes about 1 Joule.
The energy of a heartbeat is roughly 1 Joule.
Commonly used in: Scientific research, Physics education, Electronics ratings, Kinetic energy calculations, Work done.
