n. Abbr. J or j
1. The International System unit of electrical, mechanical, and thermal energy.
2.
a. A unit of electrical energy equal to the work done when a current of one ampere is passed through a resistance of one ohm for one second.
b. A unit of energy equal to the work done when a force of one newton acts through a distance of one meter. See Table at measurement.

## 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. Symbol: J
[C19: named after James Prescott Joule]

## joule

(dʒul, dʒaʊl)

n.
the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves through a distance of one meter in the direction of the force. Abbr.: J, j

## joule

(jo͞ol, joul)
A unit used to measure energy or work. One joule is equal to the work done when a force of one newton acts over a distance of one meter.

## joule

1. A unit of work or energy transfer. 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 (1818–89).

They determined that the heat content has increased by around 370 Zettajoules since 1955.
Specifically, oceans absorbed 337 zettajoules of energy between 1960 and 2015, 13 percent more energy than the Intergovernmental Panel on Climate Change's estimate for the same period.
Researchers found that around 150 zettajoules (a&nbsp;zettajoule is 1 sextillion joules) of energy were put into the ocean from 1865 to 1997, but then, over just the&nbsp;next 18 years, the oceans absorbed another 150 zettajoules of energy.&nbsp;That is roughly&nbsp;the amount of heat energy in 500,000 lightning bolts&nbsp;per second, according to climate change blog Science Skeptic.
