You can't.
The largest number of watts an appliance can safely use on a 120V circuit protected by a 25A breaker is 3000 watts. You calculate this by multiplying the voltage (120V) by the amperage (25A). This gives you a maximum power capacity of 3000 watts on this circuit.
To calculate watts, you can use the formula: Watts = Volts × Amps. For a 120V, 60Hz, 12A circuit, it would be: 120V × 12A = 1,440 watts. Therefore, the circuit uses 1,440 watts.
Yes, considering you can do that on 15 amp breaker easy.Experience in construction field. The worst that will happen is that the breaker will trip off after a few minutes.In the formula W = A x V. W = 20 x 120 = 2400 watts. If you want you can operate two 1000 watt lamps from a 20 amp breaker operating on 120 volts.
1800 watts will require a 20 amp circuit. Kitchen countertop outlets are usually, but not always, 20 amp circuits.
That's easy. Depending on the amount voltage will determine the amount of wattage, since we know the value of the current. Lets take 120 VAC times 15 Amps = 1800 watts. When my wife and me have the small electric heater running in the bedroom during the morning before and she uses her hair dryer, it blows the breaker. Then I have to run downstairs and reset the breaker. The heater runs at around 9 Amps and the hair dryer draws around 10 Amps. 19 Amps blows the breaker. The more it blows the weaker it gets. Why would one want to know the amount of wattage on a breaker, when mainly were interested in the amonut of current ratings.

Check the wattage of the device that plugs into the adapter. If the device's wattage is lower that 25 watts then the answer is yes. If the device's wattage is higher that 25 watts then the answer is no.
Answer for the US: Breakers are rated in amps, not watts. However, a 15A breaker can handle 15 amps, or about 1800 watts (using 120V), or 3600 watts (using 240V). However, this is only rated for noncontinuous loads (those not lasting for more than three hours). For continuous loads (loads lasting three hours or more), one must derate the circuit breaker by 80%. So for continuous loads, that same breaker should only have 1440 watts (using 120V), or 2880 watts (using 240V) on it.
To calculate watts, you can use the formula: Watts = Volts × Amps. For a 120V, 60Hz, 12A circuit, it would be: 120V × 12A = 1,440 watts. Therefore, the circuit uses 1,440 watts.

You need amps
15 amp breaker.
A 15-amp breaker can handle a maximum load of 1800 watts (15 amps x 120 volts). However, it is recommended to only load a circuit up to 80% of its capacity, so in practice, you should only use up to 1440 watts on a 15-amp breaker.
360 watts
The formula you are looking for is I = W/E. Amps = Watts/Volts.
