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)

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 107 ergs or 1 watt second and 100 rad.

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

the SI unit of energy, being the work done by a force of 1 newton acting over a distance of 1 meter. Symbol J.

Energy equivalence: 1 bbl oil = 6 GJ EJ: Exajoules (10^15 joules)
If the target were the amount of energy needed to provide nine billion people with the per capita consumption that Australians are likely to have risen to by 2050 then, given the anticipated growth rate, the target is 9 billion x circa 200 giga-joules (GJ) x 2, that is, 3,600 exajoules (EJ)--an EJ is equivalent to the energy content of approximately 42 million tonnes of coal.
35 exajoules (332 trillion BTUs) of energy from wood in 2004 (USDOE 2005).
