VH to Percent Converter

Convert VH units to Percentage (%).

80%

Calculates what percentage of the parent container equals the VH value.

About VH to Percent Converter

The VH to Percent converter transforms CSS viewport height units (vh) into percentage (%) values. While both are relative units, vh is always relative to the viewport height, whereas percentages are relative to the parent element's dimensions. This conversion helps developers translate viewport-based sizing into parent-relative measurements for flexible layouts.

Formula

Percentage (%) = (vh × Viewport Height) / Parent Height

Examples

40vh (1000px view, 500px parent) = 80%
50vh (1000px view, 1000px parent) = 50%

Reference

  • VH: 1vh = 1% of viewport height (always)
  • Percentage (%): Relative to parent element's dimension
  • Context-dependent: % value changes based on parent container size
  • Example: 40vh on 1000px screen inside 500px parent = 80%

Frequency Asked Questions

What is the difference between vh and percentage?

VH is always relative to viewport height (1vh = 1% of screen height), while percentage is relative to the parent element's dimensions, making them contextually different.

How do you convert vh to percent?

Multiply vh by viewport height in pixels, then divide by the parent element's height in pixels. The result depends on parent container size.

When should I use percent vs vh?

Use percent when sizing relative to a parent container. Use vh when sizing relative to the viewport, like for full-screen sections or viewport-dependent layouts.

Can vh and percent be equal?

Yes, when the parent element's height equals the viewport height, the vh and percentage values will be equal (e.g., 50vh = 50% in a full-height parent).
