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 Hourkcal/h
Target UnitThe kilocalorie per hour (kcal/h) is a derived unit of power that quantifies the rate at which energy is transferred or converted. One kilocalorie is the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius at a standard atmospheric pressure. Consequently, when expressed as a power unit, the kilocalorie per hour indicates how much energy, measured in kilocalories, is expended or utilized in one hour. This unit is commonly employed in various fields such as nutrition, engineering, and thermodynamics to describe energy expenditure and power output.
Current Use
Kilocalories per hour are widely used in nutrition to represent the energy expenditure rate of individuals during various activities. In sports science, it is crucial for determining the energy output of athletes and optimizing training regimens. The unit is also significant in the design of heating systems and appliances, where energy efficiency is measured and reported. Its application extends to HVAC systems, where power consumption is evaluated in kilocalories per hour to ensure effective climate control in buildings.
Fun Fact
The kilocalorie is often simply referred to as a 'calorie' in dietary contexts, leading to potential confusion.

Kilocalorie per Hour
power • Non-SI
Definition
The kilocalorie per hour (kcal/h) is a derived unit of power that quantifies the rate at which energy is transferred or converted. One kilocalorie is the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius at a standard atmospheric pressure. Consequently, when expressed as a power unit, the kilocalorie per hour indicates how much energy, measured in kilocalories, is expended or utilized in one hour. This unit is commonly employed in various fields such as nutrition, engineering, and thermodynamics to describe energy expenditure and power output.
History & Origin
The concept of the kilocalorie originated in the late 19th century as scientists began to better understand thermodynamics and calorimetry. The kilocalorie was defined to standardize measurements of heat energy due to its relevance in both physical chemistry and nutrition. The unit's widespread adoption was driven by the need for a common understanding of energy conversion, especially in fields such as food science, where caloric content plays a crucial role in dietary guidelines and health.
Etymology: The term 'kilocalorie' combines 'kilo-', meaning one thousand, and 'calorie,' which is derived from the Latin 'calor,' meaning heat. This reflects its definition as one thousand calories, emphasizing its application in measuring heat energy.
