Explanation

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