Enter the radius, wind speed, air density, and efficiency factor into the calculator to determine the total power output from wind.

## Wind Power Formula

The following equation is used to calculate the wind power.

P = π/2 * r² * v³ * ρ * n

- Where P is the power in watts
- r is the radius of the turbine
- v is the velocity of the wind moving through the turbine
- p is the air density (1.2 kg/m^3)
- n is the efficiency factor (typically 40%)

## Wind Power Definition

Wind power is defined as the total amount of energy per unit time that a wind turbine can generate through the kinetic energy of moving air.
