What are Btu and Kilojoule

Definition of Btu

A British Thermal Unit (Btu) is a measure of heat energy. It is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. Primarily used in the United States, Btu is a traditional unit of heat, commonly applied in heating and air conditioning industries. It provides a convenient way to compare energy outputs from various heating sources, and it plays a critical role in energy consumption calculations.

Definition of Kilojoule

A kilojoule (kJ) is a unit of energy in the International System of Units (SI). It is equivalent to one thousand joules and is commonly used to quantify energy, work, or heat in various scientific and engineering applications. Kilojoules play a vital role in nutritional labeling, helping consumers understand the energy content of food and beverages. Its widespread use in different fields makes it a fundamental unit for energy-related calculations and comparisons.
