A watt is a rate (speed) of using energy ... 1 joule per second.
Watts is energy output. Watts is joules per second. Joules is energy.
There is no conversion, as joules measures energy and watts measures power -two different quantities!
Kilowatt is a measure of the rate of energy use. It is 1,000 Watts or 1,000 Joules per second. A kilowatt hour is 1,000 Joules per second for 3,600 seconds or 3,600,000 Joules. This means a Kilowatt hour not a rate but a measure of total energy used.
1800 joules / 1 minute = 1,800 joules / 60 seconds = 30 joules per second = 30 watts.
joule/sec
Watts is energy output. Watts is joules per second. Joules is energy.
A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts. Watts means joules per second (joules / second), or equivalently, joules is watts times seconds.A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts.

The relationship between amperes, volts, and watts is... watts = amperes * volts Confirming by looking at the fundamental units involved... watts (joules per second) = amperes (coulombs per second) * volts (joules per coulomb)

"59.4 watts" means "59.4 joules every second"
Watts is joules per second, so 50 joules in 5 seconds is 10 watts.
Those numbers describe the power used by the two bulbs, in other words how many joules of electrical energy they use per second. The 100 watt bulb uses 40 watts more.
watts

Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
Voltage is electromotive force, in joules per coulomb. Power is energy transfer rate in joules per second, also known as watts.Not asked, but answered for completeness sake, and also to show the relationship between voltage and power, current is charge transfer rate in coulombs per second. So, if you multiply voltage (joules per coulomb) by amperes (joules per second) you get watts (joules per second).
Power is energy / time, energy is power x time.This is similar to the distinction between distance and speed: speed = distance / time; at constant speed, distance = speed x time.Enery is measured in Joules, power is measured in Joules / second, a.k.a. "Watts".
