## 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 10

^{7}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) (jldbomacl) the SI unit of energy, being the work done by a force of 1 newton acting over a distance of 1 meter.## joule (J)

[jo̅o̅l]

Etymology: James P. Joule, English physicist, 1818-1889

a unit of energy or work in the meter-kilogram-second system and the SI system. It is equivalent to 10

^{7}ergs or 1 watt second and 100 rad.## 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 10

^{7}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 10^{7}ergs or 0.239 cals. Named after the physicist J.P. Joule (1818–89) who determined the mechanical equivalent of heat and showed that 4.2×10

^{7}ergs = 1 calorie (4.2 joules = 1 cal.).
