A therm is equal to how many Btu?

970.3
33,475
100,000
1,000,000

The correct answer is: 100,000

A therm is a unit of heat energy that is commonly used in the natural gas industry. It is defined as equal to 100,000 British thermal units (Btu). The British thermal unit itself is a measure of the amount of energy required to heat one pound of water by one degree Fahrenheit. Understanding the relationship between a therm and Btu is crucial for anyone working in the field, particularly in environments involving heating and energy management. Given that one therm is equivalent to 100,000 Btu, it represents a significant quantity of heat, which is relevant for calculating energy consumption in heating applications, assessing efficiency of heating systems, or understanding billing in natural gas usage. While the other quantities provided relate to different energy conversions or units, they do not represent the correct conversion from therms to Btu, making the choice of 100,000 Btu the accurate and relevant answer in this context.
