Power Unit Converter

Power represents the amount of energy transfered or converter per unit time. The power unit in the International System of Units is watt which is equal to joule per second. Power can be represented as the work done with respect to time. The power in time derivative form can be written as: $$ P = \frac{\mathrm{d}W}{\mathrm{d}t}, $$ where P, W, and t is the power, work, and time, respectively. For example if a constant force F is applied on some distance \(\mathbf{x}\), the work done is defined as $$W =\mathbf{F}\cdot \mathbf{x}, $$ while the power is determined as: $$ P = \frac{dW}{dt} = \frac{d}{dt}(\mathbf{F}\cdot \mathbf{x}) = \mathbf{F}\cdot\frac{d\mathbf{x}}{dt} = \mathbf{F} \cdot \mathbf{v}, $$ As stated the dimension of power is the energy divided by time. The watt is the unit from the International System of Units (SI) which is equal to joule per second. There are also, some other common and traditional measures and these are: the horsepower (mechanical horsepower) [hp] which is equal to 745.7 [W], ergs per second [erg/s], foot-pounds per minute, BTU per hour [BTU/h], and tons of refrigiration.
