This converter provides precise conversion calculations between the main units of measuring digital resolution, including pixels/inch, dot/inch, dot/m, and dot/mm.

Digital Image Resolution unit conversion

Enter value


\text{dot/in} = \text{dot/m} \times \frac{39.3701}{1}

\text{dot/m} = \frac{\text{dot/in}}{39.3701}

\text{dot/mm} = \frac{\text{dot/in}}{25.4}

\text{pixel/in} = \text{dot/in} \times \frac{\text{pixel/dot}}{\text{dot/in}}

Different devices and applications may use various units to specify image resolution. For example, a digital camera might capture images in pixels, while a printer might require images to be specified in dot/in for printing. Our converter ensures compatibility by allowing users to convert between these units seamlessly.

Units of measuring digital resolution:

Pixels: Pixels are the smallest individual elements of a digital image. Digital images are composed of millions of pixels arranged in a grid pattern. The resolution of an image is often expressed in terms of the number of pixels along the width and height of the image (e.g., 1920x1080 pixels for Full HD resolution).

Dots Per Inch (dot/in): DPI is a measure of the density of pixels in an inch of a digital image or printed document. It indicates how many dots (or pixels) are packed into one linear inch. DPI is commonly used in printing to determine the quality and sharpness of printed images. Higher DPI values generally result in sharper and more detailed prints.

Pixels Per Inch (pixel/in): PPI is similar to DPI but is typically used in the context of digital displays, such as computer monitors, smartphones, and tablets. PPI represents the number of pixels packed into one linear inch on a digital screen. Like DPI, higher PPI values indicate higher resolution and sharper images on digital displays.

Dots per Meter (dot/m): This unit is not commonly used in digital imaging, but it can be conceptualized as a measure of pixel density along the length of one meter. It represents the number of dots or pixels that fit within one meter horizontally or vertically. Higher DPM values indicate higher pixel density and potentially higher image resolution.

Dots per Millimeter (dot/mm): It is a more commonly used unit, particularly in printing and scanning, and represents the number of dots or pixels that fit within one millimeter horizontally or vertically.
