1 Vertical FOV (degrees) =
1.77768 Horizontal FOV (degrees)

Explanation

Formula context fixed at 16:9. VFOV converts to HFOV using trig relations on the half-angle tangent model.

Vertical FOV to Horizontal FOV is profile-bound here: the selected game/FOV 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: game/FOV profile.
  • Consistency rule: keep the same profile in mirror direction to avoid mixing incompatible mappings.
