You can view more details on each measurement unit: joule or nanojoule The SI derived unit for energy is the joule. In the field of physics, the Joule (often denoted by the symbol ‘J’) can be defined as the derived unit of energy. The joule is a unit of work and energy. Joules. Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. One joule is also equivalent to one watt-second. Although both units joule and calorie both are related to the metric system, even all of them have been considered obsolete in science since the adoption of the SI unit system. 1 joule is equal to 1000000000 nanojoule. Learn more. The power P in watts (W) is equal to the energy E in joules (J), divided by the time period t in seconds (s): P (W) = E (J) / t (s) So. or. As per the International System of Units (often abbreviated to SI), one Joule is equal to the work done on (or the energy transferred to) an object upon which a force of one Newton is acting to move the object by one metre (in the direction in which the force was applied). Note that rounding errors may occur, so always check the results. We assume you are converting between joule and nanojoule. calorie. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force's motion through a distance of one metre (1 newton metre or N⋅m). Joule. The joule (); (symbol: J), is a derived unit of energy in the International System of Units. Joule: The joule (j) is referred to as a metric unit of measurement that is equal to one newton, which is equal to kg or kilograms multiplied by meters per second squared. 1 Joule = 10 7 e r g s = 0.000239 Kilo Calories. Joule is equal to Energy transferred to an object when a force of One Newton acts on that object in the direction of its motion through a distance of one metre. joule: 1 n a unit of electrical energy equal to the work done when a current of one ampere passes through a resistance of one ohm for one second Synonyms: J , watt second Type of: energy unit , heat unit , work unit a unit of measurement for work The joule (/ dʒ aʊ l, dʒ uː l / jawl, jool; symbol: J) is a derived unit of energy in the International System of Units. One joule is equal to the work done by the force of a single newton when its points of application travels through a distance of 1 meter in the same direction as the force, so it is also equivalent to 1 watt-second or 0.2390 calories. joule (jo͞ol, joul), abbr. Joules to Kelvins Converter Units of measurement use the International System of Units, better known as SI units, which provide a standard for measuring the physical properties of matter. Joule definition, the standard unit of work or energy in the International System of Units (SI), equal to the work done by a force of one newton when its point of application moves through a distance of one meter in the direction of the force: equivalent to 107 ergs and one watt-second. A. °C)) measurement units conversion. It is equal to 1000 small calories or one kilocalorie is represented by symbol (kcal). A Joule is equal to Newton x meter, and a Newton = mass x acceleration. Use this page to learn how to convert between calories and joules. The unit for mass is kg and for acceleration is m/s^2. The American Heritage® Student Science Dictionary, Second Edition. watt = joule / second. It measures energy; usually in scientific or electrical appliances . (1 N-m) 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. Abbreviations: J, j See more. The space between molecules is smaller in metals and other solids than it is in liquids and gases. A newton is said to be as a measurement that equaling the force of energy necessary to accelerate a 1 kg object 1 meter/second. The joule is the energy equal to the force on an object of one newton at a distance of one meter. To use a real-life example, gravity exerts about 1 newton of force on the average apple. W = J / s. Example. To raise an apple one meter in the air, you must use one joule of kinetic energy. One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass. So if a Joule = Newton x meter, it equals [(kg)(m/s^2)] x m. The x meter makes the meter on top squared so you get Joules = kg x m^2/s^2. One kilowatt-hour is 3.6 megajoules: since 1 watt times 1 second equals 1 joule, 1000 watts times 3600 seconds equal 3.6 MJ. m should not be used to represent the joule whenever possible, to avoid confusion with torque. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force's motion through a distance of one metre (1 newton metre or N⋅m). One Joule is 1 Newton Metre, ie the work done or energy transfered to an object when a one Newton force acts on it over one metre. The power P in watts (W) is equal to the energy E in joules (J), divided by the time period t in seconds (s): Addition of heat at constant pressure to a gas results in. joule definition: 1. a unit of energy or work done 2. a unit of energy or work done 3. a unit for measuring energy…. Watts to joules calculator Joules to watts calculation. It can also be defined as the heat energy dissipated by a current of one ampere passing through a one Ohm resistor for one second Scientists use the joule to measure work. Joule, James Prescott 1818-1889. commented Jan 3, 2016 by luckky ramya Expert (1.8k points) The megajoule (MJ) is equal to one million (10 6) joules, or approximately the kinetic energy of a one megagram (tonne) vehicle moving at 160 km/h. Note that rounding errors may occur, so always check the results. J, unit of work work, in physics and mechanics, transfer of energy by a force acting to displace a body. The molecular structure of metals is very rigid. It is equal to a newton-meter (N-m).

How to convert from Joules to Watts in 1 single step: Step 1: It is a very simple conversion, so all you have to do is divide the Joules between the time which will convert the joules into watts. Gigajoule KE ( in Joules) = 0.5 ( a half) x the mass of the something (in kg) x the speed squared (in Meters/Second) or. Use this page to learn how to convert between joules and ergs. Raising its temperature By another definition, the joule is equal to the energy required to pass an electric current of one ampere through a one ohm resistor for one second. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre (1 newton metre or N⋅m).
