Gt [TNT](gigatonne)

Unit Gt [TNT] (gigatonne of TNT) is a unit of energy that is commonly used to express the energy released from extremely large energy sources or events, such as nuclear explosions or meteor impacts. This unit is based on the energy released by the detonation of one gigatonne (one billion metric tons) of trinitrotoluene (TNT), a standard high-explosive material.

1 Gt [TNT] is equal to 4.184 x 10^18 joules. It is a non-SI (International System of Units) and non-metric unit of energy, and is typically used to express energy release in extreme events that reach beyond the scale of everyday occurrences. This unit offers a straightforward way to compare the scale of energy release with the well-known energy of TNT explosions, making it easier to grasp the magnitude of certain events.

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.
