SwitchExplanation
Formula: focal_mm = 12.5 / (2 x tan(HFOV/2)). Why: this page keeps Super 16 12.5mm fixed, so crop factor and sensor width stay explicit for every calculation.
Super 16 12.5mm: a sensor profile with crop factor 2.88 and sensor width (horizontal) 12.5 mm, used as the fixed framing basis for this page.
Horizontal angle of view (degrees): a camera-equivalence quantity in this family that depends on the selected crop model.
Focal length (mm): a camera-equivalence quantity in this family that depends on the selected crop model.
This route is useful when you know the target horizontal framing angle and need the focal length required on Super 16 12.5mm.
This page is sensor-profile dependent rather than universal because camera equivalence changes with sensor geometry (Super 16 12.5mm).

Frequently Asked Questions
Which sensor assumptions are fixed for horizontal angle of view (degrees) to focal length mm?
Horizontal angle of view (degrees) to focal length mm is fixed to Super 16 12.5mm, crop factor 2.88, sensor width 12.5 mm.
How do I reverse deg to mm for Super 16 12.5mm?
Use the opposite-direction page for Super 16 12.5mm to convert focal length (mm) back to horizontal angle of view (degrees) with the same sensor assumptions.
Can horizontal angle of view (degrees) to focal length mm replace full lens-design simulation?
No. Horizontal angle of view (degrees) to focal length mm provides framing and geometry approximations, not full optical-model behavior.
