Rec: I always thought that 'Watts' were units of Electrical Energy !!! ??? (Conversion of the Mechanical Energy of a Generator into Electrical Energy measured in Watts (or kW, or MW).
However, You can only convert Watts into Joules per second or vice-versa 1J/s = 1 W or, 1 J = 1 W/s.
1 KWh = 3.6 Mega-Joules (MJ).
There's1000 W in a kW and 3600 seconds in an hour.

Power is measured in Watts, named after James Watt (1736-1819). Joules (named after James Prescott Joule, 1818-1889) are units of energy. Use the following equation to convert from Watts to Joules.
1 Watt = 1 Joule per second of power

How do you convert Watts to Joules?

Watts = Joules / Seconds
So multiply by the number of seconds to get the number of joules.

P = E/t; where P in Watts is energy in Joules divided by t, the time the energy is running.
In general power times time is the total energy expended. This is true for horse power times time as well as other measures of power. The trick is to specify the power and the energy in compatible, consistent units.

In the same way that you convert "miles" into "miles per hour". You divide the energy [in joules] by the time [in seconds] that it takes to transfer or convert that energy.
