About Units

Electronvolts: Electronvolts (eV) are a unit of energy commonly used in the field of particle physics. One electronvolt 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. This unit is useful for expressing energy at the atomic and subatomic scales.

Btu: British Thermal Units (BTU) are a measure of heat energy. One BTU is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. This unit is commonly used in the power, steam generation, and heating, ventilation, and air conditioning (HVAC) industries.
