Megajoules
A Megajoule (MJ) is a unit of energy equal to 1,000,000 joules. It is commonly used to measure large quantities of energy in various scientific, engineering, and industrial contexts. One megajoule represents the amount of energy required to apply a force of one newton over a distance of one million meters, or the energy transferred when one megawatt of power is applied for one second. Megajoules are often used to quantify the energy content of fuels, the work done by large machines, and the energy used or produced in industrial processes, providing a standard measure for comparing significant energy transfers and consumption.
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.
