watts vs amps?

I am building a cabin on a separate hydro generator and can only get 40 amps max. The panel has a "priority" power grid. An electrician will wire the cabin. I do not know how to plan because how many amps do the baseboard heaters require if they need 1500 watts? Thanks!

amps = watts/volts
1500 watts at 120 volts = 12.5 amps
1500 watts at 240 volts = 6.25 amps

Just knowing the amperage is not enough; you need to know the power in Watts. You need to know both the amperage and the voltage to compute power: current (amps) * voltage (volts) = power (watts). If your generator is a 240V model at 40A you will have 9,600W of power available. If your generator is only a 120V model, you will have 4,800W of power available.
