Dot per millimeter quick reference
| Dot per millimeter | Dot per inch | Dot per centimeter | Dot per meter |
|---|---|---|---|
| 1 dot/mm | = 25.4 dpi | = 10 dot/cm | = 1000 dot/m |
| 10 dot/mm | = 254 dpi | = 100 dot/cm | = 10000 dot/m |
| 100 dot/mm | = 2540 dpi | = 1000 dot/cm | = 100000 dot/m |
| 1000 dot/mm | = 25400 dpi | = 10000 dot/cm | = 1000000 dot/m |
