Explanation

HD 1280x720 has a diagonal pixel count of 1468.60478005 px. pixel_pitch_mm = (diagonal_inches x 25.4) / 1468.6047800548656. For reference, input 1 in gives 0.0172953270648 mm/pixel under this profile.

Method & Display Profile

Method basis: fixed HD 1280x720 pixel grid (1280 × 720) with one constant diagonal-pixel count for this route.
Profile reference: HD 1280x720 (1280 × 720), 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.
