900 pixels is approximately 31.75 centimeters.
The conversion from pixels to centimeters depends on the pixel density or resolution, commonly measured in pixels per inch (PPI). Assuming a standard resolution of 96 PPI, the conversion is done by converting pixels to inches first, then inches to centimeters.

Conversion Formula
The basic formula to convert pixels (px) to centimeters (cm) involves two steps. First, pixels are converted to inches by dividing the number of pixels by the screen resolution in pixels per inch (PPI). Then, inches are converted to centimeters by multiplying by 2.54 (since 1 inch equals 2.54 cm).
Formula:
cm = (pixels ÷ PPI) × 2.54
Why it works: Pixels represent digital points on a screen, and their physical size depends on the PPI. Converting to inches gives a real-world length, then converting inches to centimeters gives length in metric units.
Example calculation for 900 pixels at 96 PPI:
Step 1: 900 ÷ 96 = 9.375 inches
Step 2: 9.375 × 2.54 = 23.8125 cm
Conversion Example
- Convert 500 pixels to cm:
- Divide 500 by 96 (PPI): 500 ÷ 96 = 5.2083 inches
- Multiply 5.2083 by 2.54: 5.2083 × 2.54 = 13.23 cm
- Convert 1200 pixels to cm:
- 1200 ÷ 96 = 12.5 inches
- 12.5 × 2.54 = 31.75 cm
- Convert 750 pixels to cm:
- 750 ÷ 96 = 7.8125 inches
- 7.8125 × 2.54 = 19.84 cm
- Convert 1000 pixels to cm:
- 1000 ÷ 96 = 10.4167 inches
- 10.4167 × 2.54 = 26.47 cm
- Convert 850 pixels to cm:
- 850 ÷ 96 = 8.8542 inches
- 8.8542 × 2.54 = 22.49 cm

Conversion Definitions
Pixels: Pixels are the smallest unit of a digital image or display, representing one dot of color in a grid that makes up an image. The physical size of a pixel varies depending on the device’s resolution and screen size, affecting how large it appears in centimeters or inches.
Centimeters (cm): Centimeters are a metric unit of length equal to one hundredth of a meter. Used worldwide, centimeters measure physical dimensions, where 1 cm equals approximately 0.3937 inches, providing a standard way to express length in real-world terms.
Conversion FAQs
Why does the pixel to cm conversion depend on screen resolution?
Pixels themselves are just digital points without fixed physical size. The resolution, measured in pixels per inch (PPI), determines how many pixels fit in one inch physically. Without knowing the PPI, converting pixels to centimeters is impossible because the real size varies between devices.
Can I convert pixels to cm without knowing the PPI?
No, because pixels have no absolute size without resolution context. For example, 900 pixels on a low PPI screen is physically bigger than 900 pixels on a high PPI screen. To convert accurately, the PPI value must be known or estimated.
Is 96 PPI the standard for pixel to cm conversions?
While 96 PPI is often used as a default standard in web and screen measurements, devices vary widely. Printers and high-resolution displays can have much higher PPI, so conversions using 96 PPI may not be accurate for all situations.
Does the conversion change for retina or high-density screens?
Yes, retina and other high-density screens pack more pixels into the same physical space, increasing the PPI. Thus, 900 pixels on such screens corresponds to a smaller physical size in centimeters compared to a standard 96 PPI screen.
How can I measure the PPI of my device for accurate conversion?
You can find PPI by dividing the screen’s pixel resolution by its diagonal size in inches. Alternatively, device specs or tools/apps are available online to identify screen PPI, which helps convert pixels to centimeters correctly.
