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.
Calorie per Secondcal/s
Target UnitThe calorie per second (cal/s) is a derived unit of power that quantifies the rate at which energy is transferred or converted. Specifically, it defines the amount of energy, measured in calories, that is expended in one second. In the metric system, one calorie is equivalent to approximately 4.184 joules. Therefore, a power output of 1 cal/s equals about 4.184 watts. This unit is primarily used in contexts where biological energy expenditure is assessed, particularly in nutrition and exercise science.
Current Use
The calorie per second is utilized primarily in nutritional science and exercise physiology to assess the rate of energy expenditure. It is particularly valuable when measuring metabolic rates during physical activities or the energy requirements of various biological processes. While less prevalent in industrial applications, it serves an important role in evaluating human energy consumption and efficiency.
Fun Fact
The calorie per second is often used in fitness trackers to estimate energy expenditure during workouts.

Definition
The calorie per second (cal/s) is a derived unit of power that quantifies the rate at which energy is transferred or converted. Specifically, it defines the amount of energy, measured in calories, that is expended in one second. In the metric system, one calorie is equivalent to approximately 4.184 joules. Therefore, a power output of 1 cal/s equals about 4.184 watts. This unit is primarily used in contexts where biological energy expenditure is assessed, particularly in nutrition and exercise science.
History & Origin
The concept of the calorie as a unit of energy was introduced in the early 19th century. It was initially defined as the amount of heat required to raise the temperature of one gram of water by one degree Celsius at standard atmospheric pressure. The calorie per second emerged as a measure of power, relating energy expenditure to time, particularly in fields such as nutrition and physiology where understanding metabolic rates is essential.
Etymology: The term 'calorie' is derived from the Latin word 'calor', meaning 'heat'.
Current Use
The calorie per second is utilized primarily in nutritional science and exercise physiology to assess the rate of energy expenditure. It is particularly valuable when measuring metabolic rates during physical activities or the energy requirements of various biological processes. While less prevalent in industrial applications, it serves an important role in evaluating human energy consumption and efficiency.
💡 Fun Facts
- •The calorie per second is often used in fitness trackers to estimate energy expenditure during workouts.
- •The average adult's resting metabolic rate can range from about 1 to 2.5 cal/s, highlighting the body's energy needs even at rest.
- •The relationship between calories and watts allows for easier comparisons between energy use in biological systems and electrical systems.
