Unit Explanations
Calorie per Hourcal/h
Source UnitThe calorie per hour (cal/h) is a non-SI unit of power, defined as the rate at which energy is expended or transmitted, specifically as 1 calorie being transferred in one hour. This unit is commonly used in fields related to nutrition and exercise physiology. Power, in this context, quantifies how much energy is used or produced in a given time frame, allowing for an understanding of metabolic rates and energy expenditures in various activities. The calorie itself is a measure of energy defined as the amount of heat required to raise the temperature of one gram of water by one degree Celsius at a pressure of one atmosphere.
Current Use
Currently, the calorie per hour is extensively utilized in the fields of nutrition, exercise science, and health. It provides a clear understanding of how much energy is expended during physical activities, aiding in dietary planning and health assessments. Fitness trackers and metabolic testing often express energy expenditure in this unit, assisting individuals in managing weight and health effectively. The unit is also relevant in the design of energy-efficient systems in various industries.
Fun Fact
The calorie was originally defined by how much heat is required to raise the temperature of water, showcasing its thermal origins.
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.

The calorie itself is a measure of energy defined as the amount of heat required to raise the temperature of one gram of water by one degree Celsius at a pressure of one atmosphere.
History & Origin
The calorie was first defined in the 19th century during studies involving heat and thermodynamics. It was established to quantify the energy produced by fuels and foods. The calorie per hour emerged as a practical unit to express metabolic rates, especially in human physiology and nutrition science. The evolution of this unit reflects the growing understanding of energy expenditure in physical activities and the body’s energy requirements.
Etymology: The term 'calorie' is derived from the Latin word 'calor,' meaning heat. It was first used in the late 1800s by French chemist Nicolas Clément.
