API, OpenAPI and WebMCP documentation

Explanation

UW-FHD 2560x1080 has a diagonal pixel count of 2778.48879789 px. diagonal_cm = (2778.488797889961 / PPI) x 2.54. For reference, input 1 PPI gives 7057.36154664 cm under this profile.

Method & Display Profile

Method basis: fixed UW-FHD 2560x1080 pixel grid (2560 × 1080) with one constant diagonal-pixel count for this route.
Profile reference: UW-FHD 2560x1080 (2560 × 1080), so size, PPI, and pixel-pitch values all stay tied to the same display grid.
Consistency rule: calculator output and common-value rows keep the same fixed display profile in both directions.
