How to effectively convert pixels to milimeters.
First there are some things to consider:
- DPI. The number of points per Inch
- MM_PER_INCH. Milimeters per Inch, the standard amount of milimeters in one inch: 25.4
- PIXEL. Distance to convert to milimeters
So taking the formule:
MM=(PIXEL*MM_PER_INCH)/DPI
Lets say that your image is 72 DPI, and that you want to know how many milimeters there are in 150 pixels, so,
MM=(150*24.5)/72
MM=52.92
There you are
