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.
Kilojoule MinutekJ·min
Target UnitThe kilojoule minute (kJ·min) is a non-SI unit of power that quantifies energy transfer over time, specifically energy in kilojoules expended or utilized per minute. One kilojoule is equal to 1,000 joules, while a minute is defined as 60 seconds. Therefore, one kilojoule minute corresponds to a power output of approximately 16.67 watts, as it expresses how much energy is transferred over a minute. This unit is commonly used in fields such as nutrition and exercise science to illustrate the metabolic energy expenditure of various activities.
Current Use
The kilojoule minute is widely used in nutrition to express the energy expenditure of physical activities. It allows individuals to understand how many kilojoules they burn per minute during exercise or daily tasks. Fitness and health professionals often use this measurement to guide individuals in energy management for weight loss or maintenance. Additionally, it is applicable in various scientific research studies focusing on metabolic rates.
Fun Fact
The kilojoule is commonly used in Australia and New Zealand for food energy content, replacing calories.

Kilojoule Minute
power • Non-SI
Definition
The kilojoule minute (kJ·min) is a non-SI unit of power that quantifies energy transfer over time, specifically energy in kilojoules expended or utilized per minute. One kilojoule is equal to 1,000 joules, while a minute is defined as 60 seconds.

This unit is commonly used in fields such as nutrition and exercise science to illustrate the metabolic energy expenditure of various activities.
History & Origin
The concept of measuring energy dates back to the work of scientists like James Prescott Joule in the 19th century. The joule was established in honor of Joule's contributions to thermodynamics and the quantification of energy. The kilojoule, being a multiple of the joule, became standard in energy measurements, particularly in nutrition. The minute as a unit of time has ancient origins, derived from the Latin 'minuta' meaning 'small'. The kilojoule minute thus combines these two historical units in a practical measure for energy expenditure.
Etymology: The term 'kilojoule' comes from the prefix 'kilo-' meaning one thousand, combined with 'joule', named after physicist James Prescott Joule. 'Minute' is derived from the Latin 'minuta', meaning 'small part'.
Current Use
The kilojoule minute is widely used in nutrition to express the energy expenditure of physical activities. It allows individuals to understand how many kilojoules they burn per minute during exercise or daily tasks. Fitness and health professionals often use this measurement to guide individuals in energy management for weight loss or maintenance. Additionally, it is applicable in various scientific research studies focusing on metabolic rates.
💡 Fun Facts
- •The kilojoule is commonly used in Australia and New Zealand for food energy content, replacing calories.
- •One kilojoule is roughly equivalent to the energy required to lift a small apple one meter off the ground.
- •The average person burns around 3,000 to 4,000 kJ per day depending on activity levels.
