Therm

Therm is a unit of heat measurement that is used in various fields of science and technology. It is defined as the amount of heat required to heat one ton of water by one degree Celsius under normal conditions of pressure and temperature. One therm is equal to approximately 1.055 x 10^8 J (joules).

The therm was introduced in the United States in the early 20th century and has since been widely used in the gas industry to measure the volume of gas consumed. It is also used to calculate the cost of heat consumed in domestic settings such as home heating and hot water supply.

In the US, where the term is most common, it is defined as the amount of heat required to heat 100 thousand British thermal units (BTU). One BTU is defined as the amount of heat required to heat one pound of water by one degree Fahrenheit under standard conditions of pressure and temperature. Thus, one therm is equal to approximately 100 thousand BTU or 29.3 kilowatt-hours.

Other countries use different units for heat, such as joules (J) or calories (cal). However, the term remains popular in the United States and continues to be used to measure the volume of gas consumed and calculate the cost of heat in domestic conditions.

Thus, Therm is an important unit of heat measurement that is widely used in various fields, especially in the gas industry and domestic applications in the United States. Its use allows you to accurately measure the amount of resources consumed and determine the cost of heat.

Therm is one of the units of heat measurement. In the SI system, the term denotes the amount of heat that must be expended or released to change the temperature of 1 gram of a material taken at its thermal equilibrium temperature by one kelvin. Up to the sixth decimal place in this system, one equals 1,
