Unit Explanations
Calorie per Hourcal/h
Source UnitThe calorie per hour (cal/h) is a unit of power that quantifies the rate at which energy is expended. Specifically, it is defined as the amount of energy, measured in calories, that is transferred or converted in one hour. Since one calorie is defined as the energy needed to raise one gram of water by one degree Celsius, when this is expressed over the course of an hour, it provides a useful measure of power in various applications, especially in fields such as nutrition and exercise physiology.
Current Use
The calorie per hour is widely used in various fields, including nutrition, exercise physiology, and engineering, to quantify energy expenditure. In health and fitness, it helps individuals understand their metabolic rates and manage weight. Additionally, in the context of HVAC systems, cal/h can be utilized to measure the energy output of heating systems. Its application extends to industries focused on energy efficiency, where understanding power consumption is crucial for optimizing performance.
Fun Fact
The calorie was first defined in the context of heating water, making it unique among energy units.
WattW
Target UnitThe watt (symbol: W) is the SI unit of power, defined as the rate of energy transfer equivalent to one joule per second. It measures the amount of energy conversion or transfer that occurs per unit time. In practical terms, it quantifies the rate at which work is done or energy is consumed. The watt is a derived unit in the International System of Units (SI), and it is used extensively in various fields such as electricity, mechanics, and thermodynamics to quantify power output or consumption.
Current Use
The watt is widely used across the globe to measure electrical power, mechanical power, and heat transfer. It serves as a fundamental unit in the fields of electrical engineering, physics, and many applied sciences. It is crucial for calculating energy consumption in households, industries, and for determining the power output of engines and machinery.
Fun Fact
One watt is equivalent to 1/746th of a horsepower.

Definition
The calorie per hour (cal/h) is a unit of power that quantifies the rate at which energy is expended. Specifically, it is defined as the amount of energy, measured in calories, that is transferred or converted in one hour. Since one calorie is defined as the energy needed to raise one gram of water by one degree Celsius, when this is expressed over the course of an hour, it provides a useful measure of power in various applications, especially in fields such as nutrition and exercise physiology.
History & Origin
The concept of the calorie was first introduced in the late 18th century, with the term itself derived from the Latin word 'calor,' meaning heat. The calorie was initially defined in terms of the heating of water, which became a standard reference for energy measurement. Over the years, various definitions emerged, including the small calorie (cal) and the large calorie (kcal), with the latter commonly used in dietary contexts. The calorie per hour was then adopted as a practical unit for measuring sustained energy expenditure.
Etymology: The term 'calorie' comes from the Latin 'calor' meaning heat, and was first used in scientific literature in the early 19th century.
