Explanation

8K UHD 7680x4320 has a diagonal pixel count of 8811.62868033 px. diagonal_cm = (8811.628680329193 / PPI) x 2.54. For reference, input 1 PPI gives 22381.536848 cm under this profile.

Method & Display Profile

Method basis: fixed 8K UHD 7680x4320 pixel grid (7680 × 4320) with one constant diagonal-pixel count for this route.
Profile reference: 8K UHD 7680x4320 (7680 × 4320), 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.
