Unit Explanations
WattW
Source 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.
Kilocalorie per Secondkcal/s
Target UnitThe kilocalorie per second (kcal/s) is a unit of power that represents the rate at which energy is transferred or converted. One kilocalorie is defined as the amount of energy required to raise the temperature of one kilogram of water by one degree Celsius at standard atmospheric pressure. Therefore, one kilocalorie per second indicates that one kilocalorie of energy is being supplied or used every second. This unit is particularly relevant in fields like nutrition, exercise physiology, and engineering, where energy expenditure and power output are crucial metrics.
Current Use
The kilocalorie per second is widely used in various industries, particularly in nutrition, sports science, and engineering. In nutrition, it helps assess energy expenditure during physical activity and caloric intake in diet planning. In exercise physiology, it quantifies the power output of athletes during workouts, allowing for tailored training regimens. Additionally, in engineering, it serves to evaluate the efficiency of engines and heating systems. Its applicability in both theoretical and practical contexts makes it an essential unit in understanding energy dynamics.
Fun Fact
The kilocalorie is often referred to simply as a calorie in dietary contexts, which can lead to confusion.

Kilocalorie per Second
power • Non-SI
Definition
The kilocalorie per second (kcal/s) is a unit of power that represents the rate at which energy is transferred or converted. One kilocalorie is defined as the amount of energy required to raise the temperature of one kilogram of water by one degree Celsius at standard atmospheric pressure. Therefore, one kilocalorie per second indicates that one kilocalorie of energy is being supplied or used every second. This unit is particularly relevant in fields like nutrition, exercise physiology, and engineering, where energy expenditure and power output are crucial metrics.
History & Origin
The use of kilocalories dates back to the late 19th century when the need for a standardized unit of heat energy became apparent, particularly in the context of calorimetry. The kilocalorie was adopted as a practical unit for measuring heat energy in food and nutrition by the early 20th century, allowing for a clearer understanding of energy intake and expenditure. In the context of power, kilocalories per second emerged as a necessary unit to quantify energy output in various applications, including exercise and industrial processes.
Etymology: The term 'kilocalorie' is derived from the prefix 'kilo-', meaning one thousand, and 'calorie', which itself originates from the Latin 'calor', meaning heat.
