hJ(hectojoule)

A hectojoule (hJ) is a unit of energy in the International System of Units (SI). It represents the energy equivalent to 100 joules, where a joule is the standard unit of energy. In the field of energy, hectojoule is used to measure or describe the amount of energy transferred or converted in various systems, such as electricity, heat, work, and mechanical processes. However, it is a less common unit compared to joules, kilojoules, or megajoules, which are typically used on a larger scale.

µW h(microwatt hour)

A microwatt hour (µWh) is a unit of energy used to express small amounts of energy consumption or generation, especially in the context of low-power electronic devices or systems. It is a derived unit from the International System of Units (SI) and falls under the category of energy, work, or amount of heat.

The microwatt hour (µWh) represents one millionth (10^-6) of a watt-hour (Wh), which is a widely recognized energy unit. A watt-hour is the amount of energy consumed or generated by a one-watt device operating for one hour. Therefore, one microwatt hour is equivalent to a one-microwatt (µW) device operating for one hour or using one millionth of a watt's worth of energy for one hour.

This unit of measurement is often used in various applications such as analyzing the energy consumption of electronic components like integrated circuits, sensors, and other low-power devices that operate in the microwatt range.
