VW to EM Converter
Convert VW units to EM units.
About VW to EM Converter
The VW to EM Converter transforms viewport width units into EM values based on parent element font size. This tool assists developers in creating scalable component-based designs where sizing needs to respond both to viewport dimensions and local font contexts.
Formula
EM = (vw × Viewport Width) / (100 × Parent Font Size)
Examples
5vw (1920px view, 16px parent)
=
6em
10vw (375px view, 16px parent)
=
2.344em
Reference
- • EM relative to parent font size
- • VW relative to viewport
- • EM nesting compounds values
- • Useful for component scaling
Frequency Asked Questions
Difference EM vs REM?
EM relative to parent, REM relative to root.
Why VW to EM?
For fluid components that also respect local font sizing context.
Fractional EMs?
Yes, decimals like 1.5em are standard.
Parent font effect?
Larger parent font = smaller EM value for same VW width.
