About Pixel per Inch (PPI) (PPI)
A measure of digital display pixel density and bitmap image sampling resolution, expressing the number of addressable electronic pixels per linear inch (approx. 39.370 pixel/m). Distinct from DPI: PPI represents discrete digital color samples rather than analog ink droplets.
History: Adopted across computer monitor and digital photography standards (e.g. standard 72 PPI Mac, 96 PPI Windows, and modern 300โ460 PPI Retina/OLED mobile screens).
Common Uses: Smartphone and laptop display sharpness benchmarks, digital image file metadata (EXIF resolution tags), Photoshop canvas sizing.
About Pixel per Meter (pixel/m)
The SI coherent representation of digital image spatial sampling density, representing one addressable digital pixel per meter.
History: Standard representation in satellite imagery ground sampling distance (GSD) and geographic information systems (GIS).
Common Uses: Earth observation satellite resolution, digital orthophoto mapping, large-scale computer vision grids.
โ Frequently Asked Questions
How many Pixels per Meter are in 1 Pixel per Inch (PPI)?
There are exactly 39.370079 Pixels per Meter in 1 Pixel per Inch (PPI) (1 PPI = 39.370079 pixel/m).
What is the formula to convert Pixel per Inch (PPI) to Pixel per Meter?
The formula is: Pixel per Meter = Pixel per Inch (PPI) ร 39.370079. Since 1 Pixel per Inch (PPI) = 39.370079 Pixels per Meter, multiply the value in Pixels per Inch (PPI) by 39.370079.
How do I convert 1 PPI to pixel/m manually?
To convert 1 PPI to pixel/m: apply the formula Pixel per Meter = Pixel per Inch (PPI) ร 39.370079. Substituting gives: 1 ร 39.370079 = 39.3701 pixel/m.
