Converter Calculator

1 Horizontal angle of view (degrees) =
991.191824 Focal length (mm)

Explanation

Micro Four Thirds 17.3mm uses crop factor 2 and sensor width 17.3 mm. focal_mm = 17.3 / (2 x tan(HFOV/2)). For input 1 deg, output is 991.191823619 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.
