The answer is 4185.8. 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 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. joule synonyms, joule pronunciation, joule translation, English dictionary definition of joule.

One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass. (1 N-m) 1 terawatt hour per year = 1×10 12 Wh / (365 days × 24 hours per day) ≈ 114 million watts, equivalent to approximately 114 megawatts of constant power output. The power P in watts (W) is equal to the energy E in joules (J), divided by the time period t in seconds (s): 1 Joule is equal to 1000000 Microjoule. watt = joule / second. °C)) measurement units conversion. 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). The unit for mass is kg and for acceleration is m/s^2. or. Type in your own numbers in the form to convert the units! W = J / s. Example. Also ... the amount of energy moved when it flows at the rate of erg joule . ›› Quick conversion chart of cal to joule. A. Joule. Its substitution. 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. Joules to Kilograms 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. Scientists use the joule to measure work. A joule (/ ˈ dʒ aʊ l / or sometimes / ˈ dʒ uː l /) is a unit in the SI system.
