It depends on exactly what you are talking about.
Something that is described as "X" watts is really just a resistor of a fixed size that, when connected to the proper voltage supply, will produce "X" watts of energy (light, heat, sound, etc.)
So, if you have something that is declared as 1800W and is supposed to be connected to 120V, then you have a resistor that is of size:
120V*120V/1800W = 8 Ohm
When plugged into the proper 120V source, you will pull
120V/8Ohm = 15 Amps
If you have something that is declared as 1800W but is supposed to be connected to a 240V supply, then you have a resistor that is of size:
240V*240V/1800W = 32 Ohm
When plugged into the proper 240V source, you will pull
240V/32Ohm = 7.5 Amps
So, even though both of these things were called "1800W", the key factor is what voltage they are supposed to be driven by in order to get that 1800W. These items are not interchangeable.
The 32 Ohm device will not produce 1800W on a 120V source. It will produce only 450W and pull only 3.75 Amps.
The 8 Ohm device will not produce 1800W on a 240V source. It will produce 7200W and will pull 30 Amps.

How do you compute the 2000 watts in 220 volt to how many amps?
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
How many amps is 9000 watts?
9000 watts is zero amps. Amps are the product of amps times volts. Without a voltage stated an answer can not be given. I = W/E, Amps = Watts/Volts.
How many amps with 70 watts 13.8 Volts dc?
Watts = Volts * Amps Therefore: 70 Watts / 13.8 Volts = 5.07 Amps
How many watts are in 3 amps?
The conversion of watts to amps at a fixed voltage is governed by the equation Amps = Watts/Volts for example 12 watts/12 volts = 1 amp for a US example, a food mixer with a 400 watt motor on a 120 volt supply 400/120 = 3.33amps, fit a 5amp fuse
What is 1.5amps 115 volts equal to in watts?
There really is no fixed answer. Amps are a measure of current, while watts are a measure of work. To get the answer, you need to know either how many volts you are dealing with, or how much resistance; the relationship is W= V*I (where I is the current in amps). That said, for a typical 120 volt household current, the number of watts would be 180.

How many amps is 9000 watts?
9000 watts is zero amps. Amps are the product of amps times volts. Without a voltage stated an answer can not be given. I = W/E, Amps = Watts/Volts.
How many Watts are in 730 amps?
There are zero watts in 730 amps. Watts is the product of amps times volts. As you can see without a voltage no answer can be given.
How many amps with 70 watts 13.8 Volts dc?
Watts = Volts * Amps Therefore: 70 Watts / 13.8 Volts = 5.07 Amps
How many watts are in 3 amps?

How many amperes in a watt and how many watts in a volt?
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
How many watts in a 115 volt refrigerator?
How many Amps is the fridge pulling? Multiply the Amps by the 120V circuit you're plugging into and you'll get your Watts.
How many watts in 40 amps?
I t depends. Watts = Amps times volts. 40 amps x 120 volts =4800 watts or 40 Amps x 12 volts = 480 watts.
What is 1.5amps 115 volts equal to in watts?
There really is no fixed answer. Amps are a measure of current, while watts are a measure of work. To get the answer, you need to know either how many volts you are dealing with, or how much resistance; the relationship is W= V*I (where I is the current in amps). That said, for a typical 120 volt household current, the number of watts would be 180.
How many watt in amp?
It's watts divided by volts equals amps. Example: 1200 watts at 120 volts is 10 amps. To get the watts if you know the amps, multiply the amps times the volts. 10 amps at 120 volts is 1200 watts.
At 12 volts how many watts is 30 amps?
Watts is volts times amps, so 12 x 30 = 360 watts
How many amps are in 2000 watts?
To obtain the amperage from 2000 watts the voltage is needed. I = W/E. Amps = Watts/Volts.
