An Earth curvature calculator determines how far below the horizon the surface curves at a given distance. Earth's curvature is approximately 8 inches (20 cm) per mile squared: at 1 mile away, the ground is 8 inches below line of sight; at 10 miles, it is 66.7 feet below. This affects long-range visibility, laser leveling, and tower line-of-sight calculations.
