Converter Calculator

1 Focal length (mm) =
162.768704 Horizontal angle of view (degrees)

Explanation

1-inch sensor 13.2mm uses crop factor 2.73 and sensor width 13.2 mm. HFOV = 2 x atan(13.2 / (2 x focal_mm)) in degrees. For input 1 mm, output is 162.768703632 deg.

For Focal length to Horizontal angle of view, the active sensor profile determines the conversion constants applied to every value.

Keep the same profile in both directions to avoid mixing lookup systems that use different size mappings.

Method & Reference (Verified)

  • Method basis: profile-bound mapping; constants depend on the selected profile encoded in the route.
  • Profile reference: sensor profile.
  • Consistency rule: keep the same profile in mirror direction to avoid mixing incompatible mappings.
