One watt is the rate at which work is done when an object's velocity is held constant at one meter per second against constant opposing force of one newton.
\[\mathrm{W = \frac{J}{s} = \frac{N\cdot m}{s} = \frac{kg\cdot m^2}{s^3}}\]
\[\mathrm{W = V \cdot A}\]
\[\mathrm{W = \frac{V^2}{\Omega} = A^2\cdot\Omega}\]
In terms of electromagnetism, one watt is the rate at which work is done when one ampere (A) of current flows through an electrical potential difference of one volt (V).
Two additional unit conversions for watt can be found using the above equation and Ohm's Law.
Where ohm (\Omega) is the SI derived unit of electrical resistance.
