What is Calories?
Calories (cal) is a unit of energy and power. The calorie (cal) is defined as exactly 4.184 joules. It quantifies the energy needed to raise the temperature of one gram of water by 1°C under standard conditions. The calorie is widely used in chemistry and nutrition to express energy content [bipm-si-brochure]. The calorie was introduced in the early 19th century by Nicolas Clément and standardized internationally in the 20th century. It was adopted for practical energy measurement in chemistry and food science before the joule became the SI unit [bipm-si-brochure]. Calories remain common in food labeling, nutrition, and chemistry worldwide. The dietary Calorie (kcal) is prevalent in the US, Europe, and many countries while scientific contexts prefer the joule [bipm-si-brochure].
What is Petajoules?
Petajoules (PJ) is a unit of energy and power. A petajoule equals 10¹⁵ joules and measures very large amounts of energy. It quantifies national energy consumption, large-scale industrial processes, and natural energy resources. The joule is the SI unit of energy defined as one newton meter [bipm-si-brochure]. The joule was named after James Prescott Joule and formalized in the SI system in 1960. The petajoule, using the SI prefix peta- (10¹⁵), arose to express massive energy quantities in science and engineering [bipm-si-brochure]. Petajoules are used worldwide in energy statistics, including by the International Energy Agency and national energy departments. They quantify energy production, consumption, and reserves on a country or industrial scale [nist-cuu].
Common Misspellings
