Basic Knowledge

What is BTU (British Thermal Unit)?

BTU is a unit of heat primarily used in the United States, where 1 BTU equals approximately 1,055 joules. It is commonly seen in the specifications of air conditioning and heating equipment.

Difference Between IT and Thermochemical Calories

There are two definitions of calories in coexistence: IT calories based on the International Steam Tables (1 cal = 4.1868 J) and thermochemical calories (1 cal = 4.184 J). Although the difference is small, in precise calculations it is necessary to verify which system the values belong to.
