Unit Explanations
JouleJ
Source UnitThe joule (symbol: J) is the standard unit of energy in the International System of Units (SI). It is defined as the energy transferred when a force of one newton is applied over a distance of one meter. Mathematically, one joule is equivalent to one newton-meter (N·m) or one watt-second (W·s). In terms of electrical energy, one joule is also defined as the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. The joule is named after the English physicist James Prescott Joule, who made significant contributions to thermodynamics and the understanding of energy conservation.
Current Use
The joule is widely used in multiple scientific and engineering disciplines to quantify energy, work, and heat. In physics, it serves as a fundamental measure for energy transfer, particularly in mechanics and thermodynamics. Engineers use joules to calculate energy efficiency in machinery and electricity consumption. In nutrition, energy content in food is often expressed in joules or kilojoules, allowing for a clear understanding of energy intake. The joule is also used in international standards for energy efficiency, such as those set by the International Organization for Standardization (ISO). Countries that employ the SI system, including the UK, Canada, Australia, and most European nations, utilize the joule as the standard unit for energy measurement, ensuring consistency in scientific communication and research.
Fun Fact
The joule can also be defined in terms of calories, where 1 joule is approximately 0.239 calories.
Thermthm
Target UnitThe therm is a non-SI unit of heat energy that is commonly used in the natural gas industry and for measuring heating values. Specifically, one therm is equal to 100,000 British thermal units (BTUs), which is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. This unit provides a practical way to quantify the energy content of fuels and is particularly useful in the context of residential heating and energy billing. The therm is often used in conjunction with other energy units like joules and calories, facilitating a more holistic understanding of energy consumption and production across various applications.
Current Use
The therm is predominantly utilized in the energy sector, particularly within the natural gas industry, where it serves as a standard measure for energy content. In the United States, the therm is commonly used for billing residential and commercial natural gas consumption. Utilities often express gas usage in therms, allowing customers to understand their heating energy consumption better. This unit is also relevant in industries such as HVAC (heating, ventilation, and air conditioning), where understanding energy consumption is crucial for efficiency and cost management. In the UK, therms are similarly used in energy calculations for home heating and in industrial applications. Its use has expanded globally as countries seek to standardize energy measurements, particularly in the context of energy efficiency and emissions reporting.
Fun Fact
The therm is often used in energy billing due to its practicality in quantifying fuel consumption.

Joule
energy • SI Unit
Definition
The joule (symbol: J) is the standard unit of energy in the International System of Units (SI). It is defined as the energy transferred when a force of one newton is applied over a distance of one meter. Mathematically, one joule is equivalent to one newton-meter (N·m) or one watt-second (W·s). In terms of electrical energy, one joule is also defined as the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. The joule is named after the English physicist James Prescott Joule, who made significant contributions to thermodynamics and the understanding of energy conservation.
History & Origin
The joule was named after James Prescott Joule, an English physicist known for his pioneering work on the mechanical equivalent of heat and the first law of thermodynamics. Joule's experiments in the mid-19th century demonstrated the relationship between mechanical work and heat, leading to the establishment of the principle of energy conservation. His work laid the foundation for the study of thermodynamics and energy transfer, which ultimately influenced the definition of the joule as a unit of energy.
Etymology: The term 'joule' is derived from the name of James Prescott Joule, reflecting his significant contributions to the understanding of energy and thermodynamics.
