As we know One pixel/cm is equal to 0.1 dot/mm (1 pixel/cm = 0.1 dot/mm).

To convert Pixel/Centimeter to Dot/Millimeter, multiply your pixel/cm figure by 0.1.

Example : convert 25 pixel/cm to dot/mm:

25 pixel/cm = 25 × 0.1 dot/mm = dot/mm

To convert Dot/Millimeter to Pixel/Centimeter, divide your dot/mm figure by 0.1.

Example : convert 25 dot/mm to pixel/cm:

25 dot/mm = 25 ÷ 0.1 pixel/cm = pixel/cm
