About CM to VH Converter

The CM to VH converter enables web developers to convert physical measurements into viewport height units for responsive vertical layouts. VH (viewport height) units represent a percentage of the browser's viewport height, where 1vh equals 1% of the viewport height. This makes VH units essential for creating full-height sections, hero images, and vertically-centered content that adapts to different screen sizes.

Formula

VH = ((Centimeters × (DPI ÷ 2.54)) ÷ Viewport Height (px)) × 100

Examples

1 cm (1080px) = 3.50 vh
1 cm (1920px) = 1.97 vh
1 cm (667px) = 5.67 vh

Reference

  • • 1 vh = 1% of viewport height
  • • At 1080px viewport: 1 cm = 3.50 vh
  • • At 667px mobile: 1 cm = 5.67 vh
  • • VH units adapt to vertical screen space
