dJ(decijoule)

A decijoule (dJ) is a unit of energy in the International System of Units (SI) with the symbol "dJ". It is a submultiple of the standard SI unit for energy, the joule (J). In the field of energy, one decijoule is equal to one-tenth (1/10) of a joule, or 0.1 joules.

This unit is used to quantify or measure small amounts of energy in various applications like electrical, mechanical, thermal or chemical processes. It is not as commonly used as other multiple or submultiple units like kilojoules, megajoules or millijoules, but it can still be helpful for expressing specific energy values in smaller scales.

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.
