deV(decielectron volt)

A decielectron volt (deV) is a unit of energy used in various fields, such as nuclear, atomic, or particle physics, to represent the energy of particles or processes occurring at atomic scales. It is derived from the electron volt (eV), which is defined as the amount of kinetic energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt.

A decielectron volt is equal to one-tenth (0.1) of an electron volt, so 1 deV = 0.1 eV. Electron volts and their subunits like decielectron volts are convenient units for representing small energies, such as those encountered in atomic and subatomic processes.

To put it into perspective, the energy scale of decielectron volts is quite small compared to everyday energies. One electron volt (eV) is equal to approximately 1.602 × 10^-19 joules, and hence, one decielectron volt (deV) is equal to about 1.602 × 10^-20 joules. Since the joule is the SI unit of energy, eV and deV are more suited for small-scale energy exchanges in atomic and subatomic levels.

MMBTU [IT](million British thermal units)

MMBTU, or Million British Thermal Units (MM is the Roman numeral for one thousand times one thousand), is a unit of measurement in the field of energy. The British thermal unit (BTU) is a unit of heat used in the Imperial and United States customary systems, where one BTU is roughly equivalent to the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.

In the context of energy, the MMBTU is often used to measure the energy content of fuels, such as natural gas, oil, or coal. It represents a quantity of one million BTUs and can be used to compare the energy content of different fuels, or to quantify the amount of heat energy produced by a power plant or industrial process.

The MMBTU is an "IT" or "International Table" BTU unit, which means it's based on the IT calorie and is widely used in the global energy sector. It is important to note that the MMBTU can be converted to other energy units, such as kilowatt-hours, joules, or calories, depending on the intended application or standard used in a specific industry or region.
