What is Energy?
In simple words, energy is the ability to do work. According to the law of conservation of energy, energy cannot be created or destroyed; it can only be transformed from one form to another. This means that the total amount of energy in a closed system remains constant over time.
Energy is typically measured in the International System of Units (SI) using the joule (symbol: J). The joule is the fundamental unit of energy and is defined as the work done or energy transferred when a force of one newton acts on an object and displaces it by one meter in the direction of the force.
Fortunately, the advent of energy converter tools has simplified the process of converting between different energy units. These tools enable users to seamlessly switch between units such as Kilojoule, Joule, Kilocalorie, Calorie, Kilowatt-hour, Watt-hour, Electronvolt, British thermal unit, US therm, and Foot-pound.
