How to convert pixels per millimeter to pixels per centimeter
Pixel density relates pixel counts to physical length. Printer dots (DPI) are not necessarily image pixels (PPI); resolution alone cannot determine image dimensions without a pixel count. This tool does not resize images.
Use x for the value in px/mm, b for the intermediate value in px/m, and y for the result in px/cm.
px/cm = px/mm × 1000 ÷ 100
Worked examples
10 px/mm ≈ 100 px/cm
Step 1: (10 × 1000) ≈ 10000 px/m.
Step 2: 10000 ÷ 100 ≈ 100 px/cm.20 px/mm ≈ 200 px/cm
Step 1: (20 × 1000) ≈ 20000 px/m.
Step 2: 20000 ÷ 100 ≈ 200 px/cm.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Pixels per millimeter
Pixels per millimeter (px/mm) measures digital image resolution under the conventions above. The base value in px/m is (x × 1000), where x is the numerical value in px/mm. Factors shown here are rounded for display; calculations use the stored factor.
