Explanation

QHD 2560x1440 has a diagonal pixel count of 2937.20956011 px. pixel_pitch_mm = (diagonal_inches x 25.4) / 2937.2095601097312. For reference, input 1 in gives 0.00864766353241 mm/pixel under this profile.

Method & Display Profile

Method basis: fixed QHD 2560x1440 pixel grid (2560 × 1440) with one constant diagonal-pixel count for this route.
Profile reference: QHD 2560x1440 (2560 × 1440), 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.
