How many BTU to cool one cubic meter of air 1 degree centigrade?

To cool one cubic meter of air by 1 degree Celsius, approximately 1.2 BTUs are needed. This is based on the specific heat capacity of air, which is about 1.005 kJ/kg·K, and the density of air, which is roughly 1.225 kg/m³. Therefore, cooling one cubic meter of air by one degree requires around 1.2 BTUs.
