1 PPMM = 25.4 PPI
Full precision:25.4 PPI
Step-by-Step Solution
To convert 1 ppmm to ppi, we multiply by 25.4 because one pixels per millimeter equals exactly 25.4 ppi.
1 pixels per millimeter = 25.4 ppi
Since each pixels per millimeter contains 25.4 ppi, we multiply our value by this factor:
1 × 25.4 = 25.4 ppi
So 1 ppmm = 25.4 ppi.
Quick check: 25.4 ÷ 25.4 = 1 ppmm
Example Conversions
Example 1: 1 PPMM = 25.4 PPI
1 × 25.4 = 25.4
1 × 25.4 = 25.4
Example 2: 5 PPMM = 127 PPI
5 × 25.4 = 127
5 × 25.4 = 127
Example 3: 10 PPMM = 254 PPI
10 × 25.4 = 254
10 × 25.4 = 254
