As we know One pixel/mm is equal to 1000 pixel/m (1 pixel/mm = 1000 pixel/m).

To convert Pixel/Millimeter to Pixel/Meter, multiply your pixel/mm figure by 1000.

Example : convert 25 pixel/mm to pixel/m:

25 pixel/mm = 25 × 1000 pixel/m = pixel/m

To convert Pixel/Meter to Pixel/Millimeter, divide your pixel/m figure by 1000.

Example : convert 25 pixel/m to pixel/mm:

25 pixel/m = 25 ÷ 1000 pixel/mm = pixel/mm
