As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.
IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS.
This is only valid in parts of the work using 110/220 Volt split phase power system. There will be 110V from each of the hot leads to ground/neutral, so connect your outlet to only one of the hot leads, the neutral lead and the earth ground lead. This may be a problem with a dedicated 220V circuit as there will likely be no neutral line. Another note - this could well cause an unbalanced electrical load across the two pole breaker. If the breaker has a rating of 20A and the 110V circuit draws much of that current, the heater will likely trip the breaker.
If you need a 220v circuit at only 15 or 20 amps: Get a new breaker to replace your 110v single pole breaker with a 220v double pole breaker. (You cannot exceed the original breaker's amperage rating unless you also replace the wire with a larger size). Shut off the panel's main breaker (the wires coming into the main breaker will remain hot, so don't touch them.) Remove the old 110v circuit's neutral (white) from the neutral bus bar in your distribution panel. Remove the old 110v circuit's hot (black) from the old 110v breaker. Remove the old 110v breaker. Install the new 220v breaker in place of the old breaker. (This may require you to rearrange some breakers if the old breaker was in between others) Reconnect the black wire to one terminal of the 220v breaker, and reconnect the white wire to the other terminal. Turn on the main breaker, and your new 220v breaker. Before you do this, be sure where the actual circuit goes. Changing 110v to 220v if the circuit is feeding regular 110v receptacles will cause damage to devices plugged into them. Be sure you remove all 110v devices (receptacles) from the circuit before converting it. If you need a 220v circuit for a dryer or other large appliance, your existing wiring will not be sufficient to do the above. You will need to install a new breaker and wiring. For this task, you should consult a professional electrician.
No, and if you don't have a 220v outlet, you will need an electrician to run a #8 copper wire with a direct line to the electrical panel (40 or 50 amp), depending on the oven's requirments - check the manual.
Typically you need 4 conductors. The hot wires are usually red and black. The neutral is white and the ground is green. If you put a volt meter across red and black you'll get 220 VAC. If between neutral and either hot 110 VAC.
You need a 220V cartridge fuse block open, not just two 110V fuses. Fusing a 220V device with two 110V fuses at the panel is dangerous and doesn't meet code. If you have a 220V fuse block open, simply wire the two hots to the block, and then wire the neutral and ground normally. If you have fuses make sure the box and the feed can handle a clothes dryer. It may be wise to have an electrician evaluate the system for safety.

You'll need to contact an electrician who will pull a new wire for you. If you only have 2 wires on the 240 line, you don't have a neutral or a ground; both of which are essential for a modern electric range.

To answer the exact question, 220 Volts RMS is the voltage of a supply of electric power which is twice as big as 110 Volts RMS. Note: ordinary electrical test meters (multimeters) normally measure the RMS value, not the peak value, when they are used to measure an amount of AC voltage or current. Scroll down to related links and look at "Difference between RMS voltage, peak voltage, and peak-to-peak voltage". Further notes: RMS is an acronym for 'Root Mean Square'. In essence, it's an overall average voltage rating which tells you the 'real work' which can be done by a supply of power, or, in other words, it is a truer representation of the overall power profile delivered over time by an alternating voltage supply.To determine an RMS voltage of a sine wave (as is used in AC mains power distribution), you measure its peak voltage and multiply it by .707, which will give you the RMS voltage.So a 110 Volt RMS mains supply actually has a peak voltage of about 155.6 Volts and a 220 Volts RMS mains supply actually has a peak voltage of about 311.2 Volts.
Phase, if you are referring to line, as power line from pole.
Should be ok provided you do not draw too much current.
It is the line to line voltage divided by 1.73. 600V / 1.73 = 347V 480V / 1.73 = 277V 380V / 1.73 = 220V 208V / 1.73 = 120V
Assuming that this question is about adapters for traveling to another country (not USA) then 230V is the equivalent of 220V. Just purchase a suitable adapter.
