Watt-hour
A Watt-hour (Wh) is a unit of energy that measures the amount of electrical energy consumed or generated over time. One Watt-hour is equivalent to one watt of power used or produced for one hour. This unit is commonly used to quantify energy usage in households, industries, and various devices. For instance, a 100-watt light bulb running for 10 hours consumes 1000 watt-hours, or 1 kilowatt-hour (kWh). Watt-hours are essential for understanding energy consumption, billing in electric utilities, and managing energy efficiency.
Kilojoules
A Kilojoule (kJ) is a unit of energy equal to 1,000 joules. It is commonly used to measure energy in various scientific and engineering contexts, as well as in nutrition to quantify the energy content of foods. One kilojoule is the amount of energy required to apply a force of one newton over a distance of one kilometer, or the energy transferred when one kilowatt of power is applied for one second. Kilojoules are used in fields such as physics, chemistry, and engineering to quantify work, heat, and energy, providing a standard measure for comparing energy content and transfer across different systems and processes.
