Calculation method and processing rules
Diagonals of the pixels are divided by inches diagonals to get the PPI, and then the length and width pixels are converted into millimeters.
scope of use
Assuming that the pixels are square and do not contain borders; there may be differences between the nominal size and the actual viewing area.
Is the PPI and the system display scale the same?
different. The PPI is determined by the physical size and the number of pixels, the system scale changes the display size of the interface, and does not change the pixel density of the panel itself. This tool assumes that the pixels are square and the input is a visual area size.
Will the input content be saved on the server?
This tool handles input in the browser, and does not upload files or form content. Typing practice scores are only saved in the native browser.
Why may the result be different from other tools?
Assuming that the pixels are square and do not contain borders; there may be differences between the nominal size and the actual viewing area. Please compare the input unit, rounding method, applicable rules and data version first.
