Got two rod readings and need to know the grade between them? Enter your laser level readings and distance to instantly get slope percent, slope ratio, degrees, and fall per foot — no manual math on the job site. Enter Reading A, Reading B, and the distance between points to calculate elevation difference, slope percentage, slope ratio, slope in degrees, and fall per foot. Optionally enter a known elevation at Point A to compute the exact elevation at Point B. WHAT IT CALCULATES: - Elevation difference between two rod readings - Slope as a percentage - Slope ratio (e.g., 4:1) - Slope in degrees - Fall per foot in inches - Point B elevation from known Point A elevation Built for surveyors, grading contractors, and site engineers who need quick grade checks in the field. Works completely offline.
