Please be more specific....simply replacing the breaker with a 20 amp may cause a fire; if the cable is sized for 15 amp and is overloaded. Your 15 amp breaker is probably feeding #14 wire. The use of a 20 amp breaker requires at least a #12 wire be used. Fire hazard if breakers and wiring are not sized correctly.
If the 220V circuit is dedicated, is to derate the circuit to a dedicated 110V outlet. Replace the 220V breaker with a 110V breaker and install a 110V outlet in place of the 220V outlet. If the original circuit was 20A or greater go with a 20A breaker and a 20A outlet as Airconditioners are fairly large loads. Do not exceed the current rating of the old circuit as that is all the current the existing wiring can handle.
The electrical current requirements of a wall oven can vary, depending on the heating elements used by the manufacturer. To determine the current use, refer to either the operators manual, or the service tag. The service tag may list the power consumption in Watts, in which case you'll need to convert the watts to amps using the following formula: Amps = Watts/Volts Once you've determined the current draw in Amps, OVER-rate the breaker by 20%. For example, if you calculate that the oven draws exactly 20 amps, over-rate that to 24 amps, then use the next larger size breaker and wire that is appropriate to the breaker; typically that would mean a 10 AWG wire and 30 Amp breaker. BUT!!! If you have any questions, contact a licensed electrical professional.
You would need to change a circuits voltage if your adding a load that requires 220 when the present circuit supplies 120. If you need to do so it's pretty simple! First purchase a double pole breaker at the proper amp rating. Next find the breaker in the panel that supplies power to the circuit you wish to change to 220. Turn off the breaker and pull it out. Find the neutral for that circuit. Then double check and make sure it's the right neutral. Then check one more time. Now take the neutral and the hot wire for that circuit and connect them to the double pole breaker. install the breaker into the panel and turn it on. If you connected the right neutral you'll have 220 on that circuit. If you didn't you'll know because you'll trip the breaker.
You'll need to contact an electrician to modify the circuitry of your home.For some low power devices, you can purchase a transformer that will convert to 240V, but if you're using higher current you'll need to run a 240V circuit back to the breaker panel.Always seek the assistance of a qualified electrician for these types of modifications.

You can't. That would like converting an apple into an apple basket. An Ohm is a measure of resistance to electrical current going through a circuit. The amount of electrical current is measured in Amperes. (The pressure that pushes the current through the circuit is Electromotive Force, or EMF, and is measured in Volts.
