The normal voltage in Australia is 240 volts at 50Hz. Since 2000, the mains supply voltage as specified in AS 60038 was changed to 230V with an allowed tolerance of +10% -6%. However, 240V is within tolerance and is usually found.
Australia uses a power outlet plug and socket system known as AS 3112 or "Type I". The plug has an earthing pin and two flat pins forming an inverted V-shape. There is an unearthed version of this plug as well, with only two flat V-aligned pins. These flat blades measure 6.5 by 1.6 mm and are set 30° to the vertical on a nominal pitch of 13.7 mm. The standard wall outlets are always switched for extra safety, as in the U.K.
To calculate the power in watts, you will also need to know the current in amperes. The formula to calculate power is P (watts) = V (volts) x I (amperes). If you only have the voltage (30 volts) and not the current, you cannot determine the power in watts.
To calculate the voltage, you need to know the current (amperage) as well. The formula to calculate power (watts) given voltage (volts) and current (amps) is: Power (P) = Voltage (V) x Current (I). Without knowing the current, it is not possible to directly convert watts to volts.
Normal home electrical service in most residential areas is provided at 120/240 volts. A 400 amp service would still typically be delivered at this voltage. The 400 amp rating indicates the maximum current capacity that the service can handle.
To calculate the number of watts when given volts, you also need to know the current (in amps) flowing through the circuit. The formula for power (in watts) is P = V x I, where P is power in watts, V is voltage in volts, and I is current in amps. Without knowing the current, we cannot determine the number of watts from just volts.
To determine Watts from Volts, you also need to know the current in Amperes (A) using the formula: Watts = Volts x Amperes. Therefore, 200 Volts alone cannot be converted into Watts without knowing the current. For example, if the current is 10 Amperes, then the power would be 200 Volts x 10 Amperes = 2000 Watts.
To work this out you will need to know the current that is travelling through the device. You can then find the number of volts by dividing the power (watts) by the current (amps).

It depends on how many Amps (current) are applied to the voltage. Watt = Volts x Amps. e.g. 12 volts @ 5 amps = 60 watts
It depends on the current in amps. The watts would be equal to 5 times the current, because watts equals amps times volts.
"Magnitude" means how strong it is - how much voltage (how many volts), or how much current (how many amperes).

3 things Volts, ohms, and amps
Volts and watts are different quantities and their relationship also includes the electric current. Voltage times current in amps equals the power in watts use.
