1 Horizontal angle of view (degrees) =
756.285091 Focal length (mm)

Explanation

1-inch sensor 13.2mm uses crop factor 2.73 and sensor width 13.2 mm. focal_mm = 13.2 / (2 x tan(HFOV/2)). For input 1 deg, output is 756.285090853 mm.

Horizontal angle of view to Focal length is profile-bound here: the selected sensor profile controls the mapping used by calculator and reference table.

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.
