Calorie to Therm Converter

Understanding Calorie to Therm Conversion

What is a Calorie?

A calorie (cal) is a unit of energy equal to the amount of heat needed to raise the temperature of one gram of water by one degree Celsius (from 14.5°C to 15.5°C). For food energy, we typically use kilocalories (kcal), which equal 1,000 calories.

What is a Therm?

A therm is a unit of heat energy equal to 100,000 British thermal units (BTU). It's commonly used by natural gas companies to measure energy consumption. One therm represents the energy equivalent of burning approximately 100 cubic feet of natural gas.

Conversion Formula

To convert calories to therms, use this formula:
