BTU per hour (BTU/h)

Definition: A unit of power equal to 0.293071 watts, used for measuring heat transfer rates.

History: Derived from the British thermal unit (Btu) and the hour, commonly used in heating and cooling systems.

Current Use: Used in the HVAC industry to express heating and cooling capacities.

British Thermal Unit (BTU)

History: Used in food energy labeling.

Current Use: Standard for food energy in many countries.

Calorie (Thermochemical) (cal_th)

Definition: Defined as exactly 4.184 joules.

History: Used in thermochemistry.

Current Use: Standard in thermochemical calculations.

Erg (erg)

Definition: A unit of energy in the CGS system, equal to 10^-7 joules.

Current Use: Used in physics and astronomy for small energies.

Gram Calorie (cal)

Definition: The amount of heat needed to raise 1g of water by 1°C.

History: Used in chemistry and nutrition.

Current Use: Still used in some scientific contexts.
