PX to EM, EM to PX converter tool.

PX to EM and EM to PX converter tools are functions or websites that allow designers and developers to easily convert between pixel (PX) and em unit values. Both PX and em are commonly used in web design and development, but they have their own advantages and disadvantages.PX (pixel) is a fixed unit of measurement, which means that it will always display the same size on any screen regardless of the screen size or resolution. It is often used for defining specific sizes and positions of elements on a webpage.EM (em) is a relative unit of measurement based on the font size of the element's parent container. This means that its size can be adjusted based on the font size of the container, making it a more flexible unit for responsive design. 1em is equal to 16px by default.PX to EM and EM to PX converter tools provide designers and developers with an easy way to convert between these two units. Simply input the value in the desired unit and the tool will automatically convert it to the equivalent value in the other unit. This can save time and prevent errors when designing and developing websites.
