Focal length (mm) to Horizontal angle of view (degrees) for 1-inch sensor 13.2mm
1 Focal length (mm) = 162.768704 Horizontal angle of view (degrees) ยท camera-equivalence calculation for 1-inch sensor 13.2mm
Direct Answer
On 1-inch sensor 13.2mm, a 50 mm lens gives about 15.039141 horizontal angle of view
This result uses the fixed 1-inch sensor 13.2mm sensor profile (crop factor 2.73).
For 14 Focal length (mm), this gives 50.481059 Horizontal angle of view (degrees) on 1-inch sensor 13.2mm.

SwitchExplanation
Formula: HFOV = 2 x atan(13.2 / (2 x focal_mm)) in degrees. Why: this page keeps 1-inch sensor 13.2mm fixed, so crop factor and sensor width stay explicit for every calculation.
1-inch sensor 13.2mm: a sensor profile with crop factor 2.73 and sensor width (horizontal) 13.2 mm, used as the fixed framing basis for this page.
Focal length (mm): a camera-equivalence quantity in this family that depends on the selected crop model.
Horizontal angle of view (degrees): a camera-equivalence quantity in this family that depends on the selected crop model.
This route is useful when you know the focal length on 1-inch sensor 13.2mm and want the resulting horizontal framing angle.
This page is sensor-profile dependent rather than universal because camera equivalence changes with sensor geometry (1-inch sensor 13.2mm).

Frequently Asked Questions
Which sensor assumptions are fixed for focal length mm to horizontal angle of view (degrees)?
Focal length mm to horizontal angle of view (degrees) is fixed to 1-inch sensor 13.2mm, crop factor 2.73, sensor width 13.2 mm.
How do I reverse mm to deg for 1-inch sensor 13.2mm?
Use the opposite-direction page for 1-inch sensor 13.2mm to convert horizontal angle of view (degrees) back to focal length (mm) with the same sensor assumptions.
Can focal length mm to horizontal angle of view (degrees) replace full lens-design simulation?
No. Focal length mm to horizontal angle of view (degrees) provides framing and geometry approximations, not full optical-model behavior.
