VW to EM Converter

Differences Between vw and em

Viewport Width (vw) is a relative unit that scales according to 1% of the width of the viewport. Em is a relative unit that scales according to the font size of the element it is used on. vw units are useful for scalable and responsive design, while em units provide flexibility within the context of the current element's font size.

Advantages of Using vw

Using vw units allows for better scalability and flexibility in web design. Since vw is relative to the width of the viewport, it enables elements to scale proportionally to the viewport size. This is useful for responsive design and for creating layouts that adapt to different screen sizes.

How to Convert vw to em

To convert vw to em, you need to know the width of the viewport and the font size of the current element. The formula for conversion is:

em = vw * (viewport width / 100 / font-size)

For example, to convert 2vw to em, assuming the viewport width is 1920px and the font size is 16px:

2vw * (1920px / 100 / 16px) = 2.4em
