Unit Definitions
What is a Kilojoule (kJ)?
A kilojoule (kJ) is a unit of energy equivalent to 1,000 joules. It's commonly used in various fields to quantify energy, heat, and work.
History
The kilojoule was introduced as part of the metric system in the late 19th century, derived from the joule, which was named after the English physicist James Prescott Joule. It has become a standard unit in many countries for measuring energy, particularly in food science.
Current Use
Today, kilojoules are widely used in nutrition labels and dietary guidelines, especially in regions like Australia and New Zealand, to help consumers understand energy content in food.

A joule (J) is the SI unit of energy defined as the amount of energy transferred when a force of one newton moves an object one meter. It is a fundamental unit in physics.
History
The joule was named after James Prescott Joule, who studied the relationship between heat and mechanical work in the mid-1800s. It was officially adopted as a standard unit of energy in the International System of Units (SI) in the late 19th century.
Current Use
Joules are used across various scientific disciplines, including physics, engineering, and chemistry, to quantify energy, work, and heat. They are also essential in calculations involving electricity and thermodynamics.
