Ecal [IT](exacalorie)

Ecal [IT] or exacalorie is a unit representing a large quantity of energy, which can be found in various fields like physics, chemistry, and engineering. An exacalorie is equal to 10^18 calories, meaning one exacalorie contains a quintillion (1,000,000,000,000,000,000) calories.

1 Ecal (Exacalorie) = 10^18 calories

However, in the energy domain, the unit of energy is typically Joules (J). The relationship between calories and Joules is given as:

1 calorie ≈ 4.184 Joules

As a result, one exacalorie (1 Ecal [IT]) in Joules is:

1 Ecal [IT] ≈ 4.184 x 10^18 Joules

Exacalorie is not a standard SI unit, but it is utilized in the field of energy when dealing with massive quantities of energy, like in large-scale energy production, consumption, or conversion in theoretical scenarios.

Gcal [IT](gigacalorie)

In the field of energy, a unit Gcal (gigacalorie) represents one billion calories. It is a unit of energy measurement that is primarily used in the context of heat generation and energy consumption. The term “IT” refers to the International Steam Table, which provides standardized guidelines and values for the properties of steam and water.

A calorie (also denoted as cal) is a unit of energy. In the context of energy measurements, specifically, a calorie is defined as the amount of energy required to raise the temperature of 1 gram of water by 1 degree Celsius at a pressure of 1 atmosphere. A gigacalorie (Gcal) is an energy unit that is equal to 1,000,000,000 calories.

Gcal is widely used in industrial applications, district heating systems, and power plants, among other contexts. It helps to express the energy transferred through heat or the energy consumed in large-scale operations. When comparing Gcal to other popular energy measurement units, 1 Gcal is approximately equal to 3.97 MMBTU (million British thermal units) or 4.18 GJ (gigajoules).
