lb-ft/h to cal/h

pound foot per hour

• Definition: Pound foot per hour (lb-ft/h) is a unit of power that quantifies the rate at which work is performed or energy is transferred. Specifically, it measures how much torque (in pound-feet) is exerted over time (in hours).

• Symbol: The symbol for pound foot per hour is lb-ft/h.

• Usage: This unit is commonly used in mechanical engineering and automotive contexts, where torque and power are crucial for evaluating engine performance and efficiency.

calories per hour

• Definition: calories per hour (cal/h) is a unit of power that measures the rate at which energy is expended or produced. It is particularly relevant in fields related to nutrition and thermodynamics.

• Symbol: The symbol for calories per hour is cal/h.

• Usage: This unit is often used in dietary contexts to express the energy expenditure of individuals or the energy content of food, allowing for the assessment of metabolic rates.

Origin of the pound foot per hour

• The pound foot per hour originated from the Imperial system of measurements, which includes units like pounds for force and feet for distance. It is primarily used in the United States and some other countries that utilize Imperial units, especially in engineering and automotive industries.

Origin of the calories per hour

• The calorie was originally defined in the 19th century as the amount of heat required to raise the temperature of one gram of water by one degree Celsius. The calories per hour unit evolved as a way to express energy expenditure over time, particularly in nutrition and exercise physiology.
