How many Btu's are in 1 therm?

One therm is defined as a measure of heat energy equivalent to 100,000 British thermal units (Btu). This is an important conversion factor in energy discussions, particularly in the context of natural gas consumption, where volumes of gas are often expressed in therms.

In understanding energy units, it's essential to recognize that 1 therm is specifically based on the energy content of natural gas and is established to express energy quantities in a comprehensible manner. When converting therms to Btu, the established equivalence is critical for accurate calculations in energy assessments or efficiency evaluations.

Thus, the correct value is 100,000 Btu, confirming that one therm represents this specific energy measure.
