Wind Power Density Calculator

Use one-half rho v cubed to estimate watts per square meter in the moving air stream.

Air density (kg/m³)

—Ideal wind power density

—kW/m²

—Wind m/s

—v³

This is kinetic power available in the air stream, ½ρv³. It is not turbine electrical output and does not include rotor area, Betz-limit, drivetrain, or site losses.
