You can view more details on each measurement unit: joule or nanojoule The SI derived unit for energy is the joule. The power P in watts (W) is equal to the energy E in joules (J), divided by the time period t in seconds (s): One joule is equal to the energy used to accelerate a body with a mass of one kilogram using one newton of force over a distance of one meter. 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. 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. Joules. 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. Joules versus wattsThe joule and the watt are closely related units. 5 cal to joule = 20.929 joule (1 N-m) 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. 1 cal to joule = 4.1858 joule. A. It measures energy; usually in scientific or electrical appliances . watt = joule / second. 1 Joule is equal to 1000000 Microjoule. A Joule is equal to Newton x meter, and a Newton = mass x acceleration. Named in honour of the English physicist James Prescott Joule, it equals 10 7 ergs, or approximately 0.7377 foot-pounds. 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. Note that rounding errors may occur, so always check the results. calorie. It is named after James Prescott Joule.. A joule refers to the amount of energy transferred to an object when a force of 1 newton is applied on it over a distance of 1 metre (1J = 1N × 1m).

The joule is a unit of work and energy. 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. Addition of heat at constant pressure to a gas results in. The joule is the energy equal to the force on an object of one newton at a distance of one meter. KE ( in Joules) = 0.5 ( a half) x the mass of the something (in kg) x the speed squared (in Meters/Second) or. 1 joule is equal to 1000000000 nanojoule. m should not be used to represent the joule whenever possible, to avoid confusion with torque. 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. W = J / s. Example.
