Unit Definitions
What is a Calorie (cal)?
A calorie (cal) is a unit of energy defined as the amount of energy needed to raise the temperature of one gram of water by one degree Celsius.
History
The calorie was originally defined in the early 19th century by scientists studying heat energy and was adopted in various fields like nutrition and cooking. Its widespread use in dietary contexts solidified its importance in energy measurement.
Current Use
Today, calories are commonly used to quantify the energy content of foods and beverages, making them crucial for dietary planning and nutritional guidelines.

A megajoule (MJ) is a derived unit of energy in the International System of Units (SI), equivalent to one million joules.
History
The joule was named after the English physicist James Prescott Joule, who studied energy and its transformations in the 19th century. The megajoule, being a larger unit, is used for more practical applications in energy and engineering.
Current Use
Megajoules are often used in scientific contexts, energy production, and large-scale energy calculations, including electricity consumption and fuel energy content.
