Direct Answer

1 Focal length equals 173.64034 Horizontal angle of view

This result depends on the selected profile context: sensor profile.

For 2 Focal length, this profile returns 167.319617 Horizontal angle of view.

Converter Calculator

1 Focal length (mm) =
173.64034 Horizontal angle of view (degrees)

Explanation

Cinema full-frame 36mm 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.

Focal length to Horizontal angle of view 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.
