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.
Fuel Oil Equivalent Barrel (US)FOE
Target UnitThe Fuel Oil Equivalent Barrel (FOE) is a unit of measurement used to express the energy content of petroleum products, specifically fuel oil. It is defined as the amount of energy that can be derived from one barrel (42 US gallons) of fuel oil, which is approximately 6.1 gigajoules (GJ) or 1.7 megawatt-hours (MWh). The FOE is particularly useful in energy accounting and economic analysis, allowing for the comparison of various energy sources. This unit is commonly employed in sectors such as energy production, transportation, and environmental assessment to quantify and compare energy consumption and production from various fossil fuel sources.
Current Use
The Fuel Oil Equivalent Barrel is widely utilized in various industries, including energy production, transportation, and environmental studies. In the United States, the FOE is critical for energy policy analysis, particularly within the Department of Energy and environmental regulatory bodies. It serves as a standard unit in reports regarding energy consumption, emissions, and efficiency. Countries that heavily rely on oil, such as Saudi Arabia, the United States, and Venezuela, frequently reference the FOE in their energy statistics. Moreover, energy companies use FOE to assess the performance and energy output from different fuel types, enabling better strategic planning and resource allocation.
Fun Fact
The FOE is often used in energy policy discussions to emphasize the transition from fossil fuels to renewable energy.

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.

This unit is commonly employed in sectors such as energy production, transportation, and environmental assessment to quantify and compare energy consumption and production from various fossil fuel sources.
History & Origin
The concept of measuring energy in terms of fuel oil equivalent originates from the need to standardize energy assessments across different types of fuels. In the mid-20th century, as the global demand for energy surged, especially during the post-World War II industrial boom, it became essential to develop a unified way to compare energy outputs from varied sources. The oil crises of the 1970s further emphasized the importance of understanding energy consumption metrics, leading to the formal adoption of units like the Fuel Oil Equivalent Barrel (FOE).
Etymology: The term 'fuel oil equivalent' describes a comparative measure, indicating the energy derived from fuel oil. 'Barrel' originates from the Old French word 'baril', which refers to a cylindrical container.
Current Use
The Fuel Oil Equivalent Barrel is widely utilized in various industries, including energy production, transportation, and environmental studies. In the United States, the FOE is critical for energy policy analysis, particularly within the Department of Energy and environmental regulatory bodies.
