They are measures of different things. A watt is the standard unit of measurement of electrical power. You would state the brightness of a light bulb in terms of watts. A volt is a unit of measurement of force, or pressure, in an electrical circuit. You would describe the current coming through a wire in terms of volts. These definitions are from the TechEncyclopedia at http://www.techweb.com. I added the examples.

Does a 220 volt 100 watt cost less to operate than a 110 volt with the same bulbs?
no.
A 60-watt 120 volt lamp requires morecurrrent than a 40 watt 120 volt lamp?
Yes. A 60W bulb has a higher resistance than the 40W buld. The extra resistance requires more current to light up the bulb. The fillament then glows brighter.
How much does 1 volt of electricity cost?
Electricity is not sold by the volt. It is sold by the watt, a unit of power. One watt equals one volt-ampere.
Can a 140 watt stereo power 150 watt speakers?
Yes, the speakers (150W) can handle more power than the stereo (140W) can produce. If it were the other way around (stereo more powerful than speakers), that's when you burn out your speakers.
Can an 18 watt bulb be used in low voltage outdoor lighting?
If it is an 18 watt 12 volt bulb, then yes. But an 18 watt 120 volt bulb - then no.
Where did the watt came from?
A watt is the product of amperage times voltage.
What is ampire?
Ampire. watt/volt
What is more powerful a 1000 watt motor or a 220 volt motor?
Apples and oranges. You need to compare power ratings to power ratings, not power rating to voltage rating. The bigger one (probably) wins.
Is a 230 volt motor cheaper to run than a 115 volt?
No, a watt is a watt, the voltage only changes the wire size. The power company bills you based on kilowatt hours. 1hp = 746 watts, no matter what the voltage.
How many watt of 220 volt will get by convering inverter from 200 Watt 12 volt?
Probably about 180 watts, assuming 90% efficiency.
Is 120 volts kind of the same as 1850 watts?
No, Volt and Watt is two diffrent things. 1 Volt * 1 Ampare = 1 Watt
What is the amount of power consumed by a 60 watt 220 volt lamp when it is connected across 110 volt supply?
What is the amount of power consumed by a 60 watt 220 volt lamp when it is connected across 110 volt supply?
