What are Btu and Kilocalorie

Definition of Btu

The British Thermal Unit (Btu) is a traditional unit of heat, often used in the power, steam generation, heating, and air conditioning industries. It is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. Although the Btu is not a standard unit in the International System of Units (SI), it remains widely used in the United States and other countries for various applications. Its use spans from quantifying the energy content of fuels to understanding the efficiency of heating and cooling systems.

Definition of Kilocalorie

A kilocalorie, often simply referred to as a calorie in nutritional contexts, is a unit of energy. It is defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. Kilocalories are widely used in the field of nutrition to express the energy content of food. Unlike the smaller calorie, which is used more in scientific contexts, the kilocalorie offers a more practical scale for everyday energy consumption and expenditure. It plays an essential role in dietary planning and understanding energy balance in the human body.

Conversion of Btu to Kilocalorie

1 Btu (IT)/pound/°R = 1.8 Kilocalorie (th)/kilogram/K
1 Kilocalorie (th)/kilogram/K = 0.5556 Btu (IT)/pound/°R

Example 1:
convert 5 Btu to kcal:
5 Btu = 5 × 1.8 kcal = 9 kcal

Example 2:
convert 3 Btu to kcal:
3 Btu = 3 × 1.8 kcal = 5.4 kcal
