0.707116 Horizontal FOV (degrees)

Explanation

Formula context fixed at 1:1. DFOV converts to HFOV using trig relations on the half-angle tangent model.

From Diagonal FOV to Horizontal FOV, results depend on the selected game/FOV profile and stay consistent with that profile across table rows and calculator input.

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: game/FOV profile.
  • Consistency rule: keep the same profile in mirror direction to avoid mixing incompatible mappings.
