Convert Btu (IT)/hour to calorie (th)/second

Please provide values below to convert Btu (IT)/hour [Btu/h] to calorie (th)/second [cal(th)/s], or Convert calorie (th)/second to Btu (IT)/hour.

1 Btu/h = 7.0045666826e-05 cal(th)/s. To convert Btu (IT)/hour to calorie (th)/second, multiply the value by 7.0045666826e-05; to go the other way, divide by it (1 cal(th)/s = 14276.4006014 Btu/h). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Btu (It)/hour

Btu (IT)/hour (Btu/h) is a unit of power that measures the rate of energy transfer, specifically the amount of British thermal units (IT) transferred per hour.

History/Origin

The Btu (IT) originated from the British thermal unit used in the United States and was standardized for industrial and engineering purposes. The per-hour notation became common in applications requiring power measurement, especially in heating and cooling systems.

Current Use

Btu/h is widely used in heating, ventilation, and air conditioning (HVAC) industries to specify the capacity of heating and cooling equipment, as well as in energy analysis and thermodynamics.


Calorie (Th)/second

Calorie (th)/second (cal(th)/s) is a unit of power representing the rate at which thermal calories are transferred or converted per second.

History/Origin

The calorie (th), or thermochemical calorie, was historically used to quantify energy in thermodynamics and nutrition. Its use in power measurement, such as cal(th)/s, emerged in scientific contexts to express thermal energy transfer rates before the adoption of the watt as the standard SI unit.

Current Use

Today, cal(th)/s is rarely used in scientific practice, having been largely replaced by watts (W). It may still appear in specialized fields or historical references related to thermal energy transfer rates.


Frequently Asked Questions
