About Calorie (thermochemical) (cal)

The small calorie (cal) is the energy needed to raise one gram of water by one degree Celsius at standard pressure. While largely replaced by the joule in scientific contexts (1 cal = 4.184 J exactly), the calorie remains in use in chemistry and is the basis for the food Calorie (kilocalorie).

About British Thermal Unit (BTU)

The British Thermal Unit is the energy needed to raise one pound of water by one degree Fahrenheit. Despite being an imperial unit, the BTU remains standard in the US for rating HVAC systems (a typical home furnace produces 80,000-100,000 BTU/h) and for natural gas pricing.
