Newton units joule9/4/2023 ![]() ![]() m should not be used to represent the joule whenever possible, to avoid confusion with torque.Even though the joule is algebraically equal to the N These units however, are different, and should be considered as such. BTU to Joule BTU to kcal BTU to Kilowatt-Hour BTU to MBTU BTU to Newton-Meter. m (Newton-meter), which is equivalent to the SI unit for torque. Moment of force unit conversion between newton meter and pound-force inch.One of the dimensional representations of a joule is the N Practical examples of energy measurement using joules include the energy required to lift objects, the energy released when objects fall, the heat required to raise temperature, and the kinetic energy of moving objects. He also discovered the relationship between heat and mechanical work, leading to the law of conservation of energy, and subsequently, the first law of thermodynamics.Ĭurrent use: As an SI derived unit, the joule is used within a variety of scientific contexts. ![]() 1 kilowatt-hour kWh 3600000 joule J kilowatt-hour to joule, joule to kilowatt-hour. History/origin: The unit, joule, is named after James Prescott Joule, an English physicist and mathematician who helped develop the Kelvin scale. joule J 1 kilojoule kJ 1000 joule J kilojoule to joule, joule to kilojoule. It has a number of representations both in SI base units as well as other SI units such that: It is also defined as the energy dissipated as heat when a 1 ampere electric current passes through a resistance of one ohm in the course of one second. It is defined as the energy transferred to an object when a one newton force is applied to the object in the direction of its motion through a distance of one meter. Jouleĭefinition: A joule (symbol: J) is a derived unit of energy in the International System of Units (SI). As such, the use of the newton-meter as a unit of work or energy is discouraged to avoid confusion regarding whether energy or torque is being expressed. History/origin: The use of the newton-meter as a unit of work or energy is derived from the fact that the joule, the SI (International System of Units) unit of energy, is dimensionally equivalent to the newton-meter.Ĭurrent use: The newton-meter is more commonly used as a unit of torque rather than as a unit of work or energy. In this use, it is defined as the energy transferred to an object by a one newton force acting on that object in the direction of its motion over a distance of one meter. m) is sometimes used as a unit of work or energy and in this context is equal to the joule, the SI unit of energy. ![]()
