Converter Calculator

1 Horizontal angle of view (degrees) =
452.625168 Focal length (mm)

Explanation

Smartphone 1/1.7" class uses crop factor 4.55 and sensor width 7.9 mm. focal_mm = 7.9 / (2 x tan(HFOV/2)). For input 1 deg, output is 452.625168011 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.
