Yes, Transformers which operate on 110 - 120 Volts exist. This question is probably incomplete as it only mentions one voltage: it could be for the primary or the secondary or for a single-winding auto-transformer. The missing information cannot be guessed...
To convert 7620 volts to 240 volts, you would need to use a transformer. The transformer would step-down the voltage from 7620 volts to 240 volts. The ratio of the turns on the transformer primary and secondary windings determines the voltage transformation.
No, it is not recommended to convert a Yamaha Clavinova from 120 volts to 240 volts. This could damage the instrument and void any warranty it may have. It is best to purchase a Yamaha Clavinova that is already rated for 240 volts if needed.
to derive 120 volts from 480 volts you have to use a transformer, based on your needs. If you needed 100 amps at 120 volt single phase you would need a 12kva transformer. This is just an example.
You can use a step-up transformer to convert 120 volts to 230 volts for your well water pump. Make sure the transformer is rated for the appropriate power output needed by the pump and that it is installed correctly to ensure safe operation. It is recommended to consult a professional electrician for assistance with this type of electrical work.
You can use a transformer to step down the voltage from 440 volts to 380 volts. Make sure to use a transformer that is rated for the required input and output voltage, and have a qualified electrician perform the installation for safety.
Volts cannot be converted to amps. If you mean convert 220v to 12 volts output, then you need a 220v to 12 v step down transformer with the VA or watt rating you require.
To convert 7620 volts to 240 volts, you would need to use a transformer. The transformer would step-down the voltage from 7620 volts to 240 volts. The ratio of the turns on the transformer primary and secondary windings determines the voltage transformation.
If you get 220 volts instead of 208 volts it means that the transformer supplying the circuit is wired in Delta with one of the legs center-tapped to ground.
I guess you have a chiller unit suitable for 380Volts and you have a source voltage of 220V. You can step up 220Volts to 380 volts with a suitable rated step up transformer.
If it is AC voltages you need to convert, you need to find a transformer to do this job. Without knowing the application it is hard to guess what you are trying to do.

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.

A transformer is needed to convert 110 v to 220 v or vice versa. This type of transformer is commonly used in Europe for power tools in the building trade which run from a portable 110 v transformer with a centre-tapped earth for safety so that each side is only 55 v to earth. A 3 kVA transformer for this purpose costs about £80.
If it is AC then you don't need a formula, you just need a transformer.
