Horizontal angle of view (degrees) to Focal length (mm) for Drone 1-inch class
1 Horizontal angle of view (degrees) = 756.285091 Focal length (mm) ยท camera-equivalence calculation for Drone 1-inch class
Direct Answer
On Drone 1-inch class, a 50 horizontal angle of view needs about a 14.153746 mm lens
This result uses the fixed Drone 1-inch class sensor profile (crop factor 2.73).
To reach 14 Horizontal angle of view (degrees), you need 53.752686 Focal length (mm) on Drone 1-inch class.

SwitchExplanation
Formula: focal_mm = 13.2 / (2 x tan(HFOV/2)). Why: this page keeps Drone 1-inch class fixed, so crop factor and sensor width stay explicit for every calculation.
Drone 1-inch class: a sensor profile with crop factor 2.73 and sensor width (horizontal) 13.2 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 Drone 1-inch class.
This page is sensor-profile dependent rather than universal because camera equivalence changes with sensor geometry (Drone 1-inch class).

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 Drone 1-inch class, crop factor 2.73, sensor width 13.2 mm.
How do I reverse deg to mm for Drone 1-inch class?
Use the opposite-direction page for Drone 1-inch class 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.
