What does the unit 'therm' specifically measure?

The unit 'therm' specifically measures energy consumption, particularly in the context of natural gas. One therm is equivalent to 100,000 British thermal units (BTUs) and is used to quantify the amount of heat energy produced or consumed. It reflects the energy content of fuels, making it a crucial unit in the energy sector, especially for billing in residential and commercial settings where natural gas is used for heating and cooking. This measurement provides a standardized way to compare and assess energy use across different applications and energy sources.
