About This Tool
The Angle Calculator is a fundamental utility for any construction project, especially boat building where precise angles are paramount. By simply entering a vertical 'rise' and a horizontal 'run', you can instantly find the corresponding angle in degrees, its slope as a percentage, and other useful related values. This tool is perfect for determining bevels, deadrise, deck camber, or any other angle defined on a set of plans.

Key Concepts:

Rise: The vertical change between two points.
Run: The horizontal change between two points.
Angle: The inclination of a line, calculated using trigonometry (arctan(rise/run)).
Slope: The steepness of the line, expressed as a percentage.
