What are Btu and Calorie

Definition of Btu

The British Thermal Unit (Btu) is a unit of heat energy commonly used in the United States. It represents the amount of energy needed to heat one pound of water by one degree Fahrenheit. Originating from Victorian-era science, the Btu remains vital in various fields including heating, air conditioning, and energy management. Engineers and scientists use Btu in calculations involving energy efficiency and fuel consumption. Despite the international preference for the joule, the Btu continues to be a significant unit in industries where precise measurements of thermal energy are critical.

Definition of Calorie

A Calorie, in the context of nutrition and thermodynamics, is a unit of energy. It is defined as the amount of heat needed to raise the temperature of one gram of water by one degree Celsius. Originally developed in the early 19th century, the Calorie has become a fundamental unit in fields related to food energy and dietary management. Scientists and health professionals use it to quantify the energy provided by foods and beverages. Although the joule has gained prominence in scientific contexts, the Calorie remains a popular unit in nutrition and dietetics.
