Whole metres (0+).
Extra millimetres (0–999). We’ll auto‑carry if you type ≥1000.
Typical range: 0.1° to 89.9°. (0° gives 0 lift; 90° is not possible.)
Enter a horizontal measurement and a required angle. The calculator returns the vertical set‑out needed at 90° to achieve that angle (your hypotenuse line).
Output shown in mm and metres + mm.
