Watts is volts x current.

Ohms law means you can algebraically substitute V = I * R

P = i^2 * R

P = VI

P = V^2 * R

    Should be P = V^2 / R, but other than that, yes exactly.

    Everyone saying "it scales with voltage" or "it scales with resistance" are describing different sides of the same coin. At the end of the day, the thing we're talking about is just power, you can pick and choose whichever version of the power formula that you want.
