Knowing any two of the values of a circuit ,one can determine (calculate) the third using "Ohm`s law.

If the circuit has a current of 2 amperes, and a resistance of 1"Ohm (<these are the two knowns )

Then according to Ohm`s law Voltage equals Current multiplied by Resistance .

( V=2Amperes x 1 Ohm = 2 Volts.

You cannot convert watts to amps, since watts are power and amps are coulombs per second (like converting gallons to miles). HOWEVER, if you have at least least two of the following three: amps, volts and watts then the missing one can be calculated. Since watts are amps multiplied by volts, there is a simple relationship between them.
