The watt is a unit of power. It is a Newton meter per second, or can be given as a joule per second. We often encounter it in electrical calculations, and it is the unit of power for applications there. The formula for power is given here:
P = I x E
In this expression, the power (P) in watts is equal to the current (I) in amps (or amperes, if you prefer) times the voltage (E) in volts.
The simplest example of a watt would be the amount of power that you would have if you had one volt at one amp of current. Or, to put it another way, 1 volt X 1 Amp=1 Watt. To go further, 12 volts at 1 amp equals 12 watts. This is for direct current measurement.
For AC voltage, it varies in that you would multiply the volts by .707 (AC RMS voltage), then multiply by the amps to get your watts total.

How many lumen's in a 150 watt flood light?
around 21,000 average 100 watt bulb is around 1400 lumens. That's 14 lumens per watt. 14X1,500 = 21,000
Do a 12 volt 50 watt bulb and a 230 volt 50 watt bulb draw the same current?
A 50 watt bulb designed to run on 12 volts takes 4.17 amps. A 50 watt bulb designed to run on 230 volts takes 0.217 amps.
Does the higher the watt have a hotter temperature?
Yes
How many amps are required to run a 240-volt 5500-watt water heater element?
Current (Amps) = Power (Watt)/Voltage (V) Therefore a 4500W heating element will draw 18.75A = 4500W/240V

How many giga watts is a exa watts?
there is one Giga Giga watt in one Exa watt. So one Exa watt = one Giga Giga watt or 109 Giga watt or one Exa watt = 1018 watt and one Giga watt = 109 watt then one Exa watt = 109 Giga watt or one Exa watt = one billion Giga watt = one thousand million Giga watt

What is gegawatt?
not gega watt ,it is gaga watt , you have to start from 1 watt 1000 watt = 1 k watt 1000 000 = 1 mega watt 1000 000 000 = 1 gaga watt example : your home need 5 k watt = 5000 watt , but this mega watt or gaga watt amount generated from huge turbine s ,to feeding cites needs in electricity demand .
