You haven't provided enough information. You can't "convert" newtons to joules, as they do not represent the same type of unit. The newton is a unit of force, whereas the joule is a unit of energy. A joule is defined in the electrical context as "a unit of electrical energy equal to the work done when a current of one ampere is passed through a resistance of one ohm for one second." and in the physical context as "a unit of energy equal to the work done when a force of one newton acts through a distance of one meter." So, it seems to me that if this is a physics problem, then you also need a distance to be able to calculate the amount of energy (you would multiply the newtons by the metres).
