About EM to VW Converter

The EM to VW converter bridges two different CSS unit systems: relative font-based units (EM) and viewport-based units (VW). This tool is invaluable for creating truly responsive typography and layouts that adapt smoothly to different screen sizes.

Formula

VW = ((EM × Base Font Size) ÷ Viewport Width) × 100

Examples

2em (16px base, 1920px view) = 1.67vw
1.5em (16px base, 1440px view) = 1.67vw
1em (20px base, 768px view) = 2.6vw

Reference

  • • 1vw = 1% of viewport width
  • • VW scales with browser window size
  • • EM scales with parent font size
  • • Combine with calc() or clamp() for best results
