1 Focal length (mm) =
173.64034 Horizontal angle of view (degrees)
Explanation
Full-frame 36mm width uses crop factor 1 and sensor width 36 mm. HFOV = 2 x atan(36 / (2 x focal_mm)) in degrees. For input 1 mm, output is 173.64033976 deg.
From Focal length to Horizontal angle of view, results depend on the selected sensor profile and stay consistent with that profile across table rows and calculator input.
