Converting 9 volts to 230 volts would require a pretty hardcore step up transformer (Expensive) and you probably wouldn't have enough current to sustain the load.
See discussion page for more information.
The only way to do that is with a transformer. They make inline transformers that convert 230 to 115 and they simply plug in inline.
230 Volt

16A
With an appropriately rated DC to DC converter.
That is called an inverter.
If a precision voltage is needed from 200 to 230 an auto transformer could be used. If the load is a 230 volt motor to be operated on 200 then add 15% to the nameplate full load amperage for the calculation for overload protection.
Yes, you can use a 230 volt device on a 240 volt supply.

no
No.
no
No totally different
If you are talking about a 6 volt coil, yes, so long as the contacts are rated for the 230 volt circuit. If you are talking about 6 volt contacts, no, absolutely not.
There in no quick and inexpensive way of doing this conversion. A transformer would have to be used and this type of winding is not common. 277 volts is the wye voltage of a three phase 480 volt system.
230 Volt
Yes, 220 volts is in the same voltage classification as 230 volts.
