PX to MM Conversion Formula
To convert pixels (PX) to millimeters (MM), you need to know the screen DPI (dots per inch) or PPI (pixels per inch) of the display. Once you have this value, you can use the following formula:
Millimeters = Pixels * 25.4 / DPI
Example of PX to MM Conversion
Example 1: PX to MM Conversion
For example, if you have 100 pixels and the DPI is 96, the calculation would be:
Millimeters = 100 * 25.4 / 96 ≈ 26.67 millimeters
PX to MM Conversion Table (up to 20 entries)
Since the conversion depends on the DPI, a table with specific conversions would vary based on the DPI. Here’s a general example for a DPI of 96:
Pixels | Millimeters |
---|---|
10 | 2.67 |
20 | 5.33 |
30 | 8.00 |
40 | 10.67 |
50 | 13.33 |
60 | 16.00 |
70 | 18.67 |
80 | 21.33 |
90 | 24.00 |
100 | 26.67 |
110 | 29.33 |
120 | 32.00 |
130 | 34.67 |
140 | 37.33 |
150 | 40.00 |
160 | 42.67 |
170 | 45.33 |
180 | 48.00 |
190 | 50.67 |
200 | 53.33 |
PX to MM Converter FAQs
What is the conversion factor from pixels (px) to millimeters (mm)?
The conversion factor depends on the pixel density (PPI or DPI) of the display. Typically, 1 inch equals 25.4 millimeters, and 1 inch equals 96 pixels, so the conversion factor is approximately 0.2645833 millimeters per pixel (mm/px).
How do I convert pixels to millimeters?
To convert pixels to millimeters, you can use the formula: value in mm = (value in px / PPI or DPI) * 25.4
.
Why is the conversion from pixels to millimeters approximate?
The conversion depends on the screen's pixel density (PPI or DPI), which varies across different devices. Without knowing the exact PPI/DPI, conversions can only be estimated.
Can I convert any pixel value to millimeters?
Yes, you can convert any pixel value to millimeters using the formula mentioned above, adjusted for the specific PPI or DPI of the screen.
Are there tools or calculators available for PX to MM conversions?
Yes, there are online converters and software tools that can perform accurate conversions from pixels to millimeters, taking into account the screen's PPI or DPI. These tools are useful for designers and developers working on projects that require precise measurements in millimeters.
