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 quantifies energy transfer or conversion rates. It represents the amount of energy, measured in kilocalories, that is expended or utilized each second. One kilocalorie equals 1,000 calories, which refers to the energy required to raise the temperature of one kilogram of water by one degree Celsius. This unit is commonly used in fields such as nutrition, exercise physiology, and engineering to describe the power output of machines, metabolic rates, and energy requirements.
Current Use
The kilocalorie per second is widely utilized in nutrition science to determine the caloric expenditure of physical activities and in various engineering fields to assess the performance of engines and heating systems. In the fitness industry, it helps quantify energy output during exercise regimes, allowing individuals to tailor their nutrition and workout plans accordingly. Additionally, it finds application in the food industry for evaluating energy content in food products, aiding in dietary planning and labeling.
Fun Fact
The kilocalorie is often referred to simply as '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 quantifies energy transfer or conversion rates. It represents the amount of energy, measured in kilocalories, that is expended or utilized each second. One kilocalorie equals 1,000 calories, which refers to the energy required to raise the temperature of one kilogram of water by one degree Celsius. This unit is commonly used in fields such as nutrition, exercise physiology, and engineering to describe the power output of machines, metabolic rates, and energy requirements.
History & Origin
The kilocalorie, originally defined in the 19th century, stems from the calorie, a unit historically linked to heat energy. The calorie itself was conceptualized in the early 1800s, gaining prominence through the works of scientists such as Joule and later the establishment of the kilocalorie as a more practical unit for larger energy measurements. The kilocalorie per second emerged as a means to express power in terms of energy per unit time, facilitating calculations in metabolic studies and engineering applications.
Etymology: The term 'kilocalorie' combines the prefix 'kilo-', meaning one thousand, with 'calorie', derived from the Latin 'calor', meaning heat.
Current Use
The kilocalorie per second is widely utilized in nutrition science to determine the caloric expenditure of physical activities and in various engineering fields to assess the performance of engines and heating systems. In the fitness industry, it helps quantify energy output during exercise regimes, allowing individuals to tailor their nutrition and workout plans accordingly. Additionally, it finds application in the food industry for evaluating energy content in food products, aiding in dietary planning and labeling.
💡 Fun Facts
- •The kilocalorie is often referred to simply as 'calorie' in dietary contexts, which can lead to confusion.
- •One kilocalorie is equivalent to approximately 4.184 kilojoules, making it a critical unit in both imperial and metric systems.
- •The concept of the calorie was first introduced by French chemist Nicolas Clément in the early 19th century.
