Cm to DPI Calculator

Formula

The formula to calculate the Dots Per Inch (DPI) is:

\[ DPI = \frac{D}{C / 2.54} \]

Where:

\(DPI\) is the dots per inch
\(D\) is the total number of dots in the image
\(C\) is the length in centimeters

What is Cm to Dpi?

Cm to Dpi refers to the conversion of a measurement from centimeters to dots per inch. This is often used in printing and graphic design to determine the resolution of an image. Dots per inch (Dpi) is a measure of spatial printing or video dot density, in particular the number of individual dots that can be placed within the span of one linear inch (2.54 cm). Therefore, converting cm to dpi helps in understanding the quality or clarity of an image or print.

Example Calculation

Let's assume the following values:

Total Number of Dots (D) = 3000
Length (C) = 15 cm

Using the formula to calculate the Dots Per Inch (DPI):

\[ DPI = \frac{D}{C / 2.54} = \frac{3000}{15 / 2.54} ≈ 508.47 \text{ DPI} \]

The Dots Per Inch (DPI) is approximately 508.47 DPI.
