What are Megajoule and Watt-hour

Definition of Megajoule

A Megajoule (MJ) is a unit of energy equivalent to one million joules. It's a standard unit within the International System of Units (SI) used to quantify large amounts of energy. For instance, the energy released by a lightning strike can be expressed in Megajoules, highlighting its capacity to measure significant power events and transactions in various fields such as physics, engineering, and utilities.

Definition of Watt-hour

A Watt-hour (Wh) is a unit of energy that represents the amount of work done or energy consumed when one watt of power is used for one hour. It is a smaller unit of energy commonly used in electrical applications to measure electricity consumption. For example, a light bulb rated at 100 watts operating for 10 hours would use 1 kilowatt-hour, which is equivalent to 1,000 watt-hours.
