Dot per meter quick reference
| Dot per meter | Dot per centimeter | Dot per inch | Dot per millimeter |
|---|---|---|---|
| 1 dot/m | = 0.01 dot/cm | = 0.0254 dpi | = 0.001 dot/mm |
| 10 dot/m | = 0.1 dot/cm | = 0.254 dpi | = 0.01 dot/mm |
| 100 dot/m | = 1 dot/cm | = 2.54 dpi | = 0.1 dot/mm |
| 1000 dot/m | = 10 dot/cm | = 25.4 dpi | = 1 dot/mm |
Where the dot per meter fits
