Answer:

joule

Unit system

SI derived unit

Unit of

Energy

Symbol

J 

Named after

James Prescott Joule

Conversions

1 J in ...

... is equal to ...

SI base units

kg⋅m2⋅s−2

CGS units

1×107 erg

kilowatt hours

2.78×10−7 kW⋅h

kilocalories (thermochemical)

2.390×10−4 kcalth

BTUs

9.48×10−4 BTU

electronvolts

6.24×1018 eV

In terms firstly of base SI units and then in terms of other SI units, a joule is defined below, where kg is the kilogram, m is the metre, s is the second, N is the newton, Pa is the pascal, W is the watt, C is the coulomb, and V is the volt:

The work required to move an electric charge of one coulomb through an electrical potential difference of one volt, or one coulomb-volt (C⋅V). This relationship can be used to define the volt.

The work required to produce one watt of power for one second, or one watt-second (W⋅s) (compare kilowatt-hour – 3.6 megajoules). This relationship can be used to define the watt.

The joule is named after James Prescott Joule. As with every SI unit named for a person, its symbol starts with an upper case letter (J), but when written in full it follows the rules for capitalisation of a common noun; i.e., "joule" becomes capitalised at the beginning of a sentence and in titles, but is otherwise in lower case.

Hope it helps you.

Explanation:

As you may know that,

Work done = Force × displacement

From the formula we can say that the amount of work done when a force of 1 N (Newton) moves or displaces a body to a distance of 1 m towards the direction in which force is applied is called 1 J (Joule).

Hope it helped
