joule (dʒuːl) n (Units) the derived SI unit of work or energy; the work done when the point of application of a force of 1 newton is displaced through a distance of 1 metre in the direction of the force. 1 joule is equivalent to 1 watt-second, 107 ergs, 0.2390 calories, or 0.738 foot-pound.

One joule is equal to work done by a force of one newton moved about 1 m in the direction of the force.2. (J) A unit of energy equal to the work done when a force of one newton is applied through a distance of one meter. Used instead of calorie: 1 J = 0.239 cal. Named after the British physicist J.P.

Joule.joule (jool) Symbol: J. The SI unit of energy, equal to the work done when the point of application of a force of one newton is moved one meter in the direction of the force.Joule a unit of energy and work in the International System of Units and the MKSA (meter-kilogram-second-ampere) system. It is equal to the work done by a force of 1 newton in moving a body 1 m in the direction of the force. It is named in honor of the English physicist J. Joule. In Russian the symbol is dzh; the international symbol is J. At the Second World Conference of Electrical Engineers (1889) the joule was introduced into the absolute practical electrical units as the unit of work and energy for electric current. The joule was defined as the work done at a power of 1 watt in 1 second. The International Conference on Electrical Units and Standards (London, 1908) established “international” electrical units, among them the so-called international joule. After the return to absolute electrical units (beginning Jan. 1, 1948), the ratio of 1 international joule to 1.00020 absolute joules was adopted. The joule is also used as a unit of quantity of heat. The ratio of the joule to other units is as follows: 1 joule = 107 ergs = 0.2388 calories. G. D. BURDUN joule[jül or jau̇l] (mechanics) The unit of energy or work in the meter-kilogram-second system of units, equal to the work done by a force of 1 newton magnitude when the point at which the force is applied is displaced 1 meter in the direction of the force. Symbolized J. Also known as newton-meter of energy. jouleA unit of energy or work; equals the work done by a force of 1 newton which acts over a distance of 1 metre in the direction of the force.joule the derived SI unit of work or energy; the work done when the point of application of a force of 1 newton is displaced through a distance of 1 metre in the direction of the force. 1 joule is equivalent to 1 watt-second, 107 ergs, 0.2390 calories, or 0.738 foot-pound
Joule James Prescott. 1818--89, English physicist, who evaluated the mechanical equivalent of heat and contributed to the study of heat and electricity jouleA unit of energy in the MKS system. It is equal to 10,000,000 ergs in the CGS system. Surge protectors are often given joule ratings, but this refers only to the amount of energy they can absorb, not what gets through. See CGS system.joule
joule (J) [jo̳l] the SI unit of energy, being the work done by a force of 1 newton acting over a distance of 1 meter.Joule (jūl), James P., British physicist, 1818-1889. See: joule, Joule equivalent. joule (J), (jūl), A unit of energy; the heat generated, or energy expended, by an ampere flowing through an ohm for 1 sec; equal to 107 ergs and to a newton-meter. It is an approved multiple of the SI fundamental unit of energy, the erg, and is intended to replace the calorie (4.184 J). Synonym(s): unit of heat (3) [James P. Joule] joule (J) (jūl) A unit of energy; the heat generated, or energy expended, by an ampere flowing through an ohm for 1 second; equal to 107 ergs and to a newton-meter. It is an approved multiple of the SI fundamental unit of energy, the erg, and is intended to replace the calorie (4.184 J). [James P. Joule]joule A unit of work, energy and heat. A watt-second. The joule is being used increasingly to replace the CALORIE in nutritional contexts. The calorie is equal to 4.187 J. (James Prescott Joule, 1818–89, English physicist).joule an SI unit of energy equal to 107 ergs or 0.239 cals. Named after the physicist J.P. Joule (1818–89) who determined the mechanical equivalent of heat and showed that 4.2×107 ergs = 1 calorie (4.2 joules = 1 cal.).Joule, James P., English physicist, 1818-1889. joule - Synonym(s): unit of heatJoule equivalent - the dynamic equivalent of heat.FinancialSeeJJOULE
