Therms are units of measurement used to quantify energy, specifically in the context of natural gas. One therm is equivalent to 100,000 British thermal units (BTUs), which is the amount of energy needed to raise the temperature of one pound of water by one degree Fahrenheit. This measurement helps consumers and businesses understand their energy usage and costs. In the energy industry, therms are commonly used for billing purposes, allowing customers to track their natural gas consumption. Utilities often convert gas usage into therms to provide clearer information on energy costs, making it easier for consumers to manage their energy expenses and consumption patterns.
