About CM to VW Converter

The CM to VW converter helps designers and developers translate physical measurements into viewport width units for truly responsive web design. VW (viewport width) units represent a percentage of the browser's viewport width, where 1vw equals 1% of the viewport width. This makes VW units perfect for creating fluid layouts that scale proportionally with screen size.

Formula

VW = ((Centimeters × (DPI ÷ 2.54)) ÷ Viewport Width (px)) × 100

Examples

1 cm (1920px) = 1.97 vw
1 cm (1366px) = 2.77 vw
1 cm (375px) = 10.08 vw

Reference

  • 1 vw = 1% of viewport width
  • At 1920px viewport: 1 cm = 1.97 vw
  • At 375px mobile: 1 cm = 10.08 vw
  • VW units are responsive and fluid by nature
