Convert horsepower (metric) to calorie (th)/second
Please provide values below to convert horsepower (metric) [hp (metric)] to calorie (th)/second [cal(th)/s], or Convert calorie (th)/second to horsepower (metric).
How to Convert Horsepower (Metric) to Calorie (Th)/second
1 hp (metric) = 0.175788420172084 cal(th)/s
Example: convert 15 hp (metric) to cal(th)/s:
15 hp (metric) = 15 × 0.175788420172084 cal(th)/s = 2.63682630258126 cal(th)/s

Horsepower (Metric)
The metric horsepower (hp) is a unit of power defined as exactly 735.5 watts, used to measure the power output of engines and motors.
History/Origin
The metric horsepower was introduced in the late 19th century as a standardized unit to quantify engine power, primarily in Europe, replacing traditional units like the imperial horsepower. It was adopted for consistency in engineering and automotive industries.
Current Use
Today, the metric horsepower is used mainly in automotive, engineering, and industrial contexts to specify engine power, especially in regions that utilize the metric system. It is also used in some countries for rating motor and engine capacities.
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 It may still appear in specialized fields or historical references related to thermal energy transfer rates.
