VH to MM Converter
Use this free online vh to mm converter tool to convert viewport height units to millimeters. Millimeters are an absolute unit used for precise print measurements. This converter translates responsive viewport sizing to precise metric dimensions.
To convert vh to millimeters, multiply the vh value by viewport height and divide by 100 to get pixels, then multiply by 25.4 and divide by 96. The default viewport height is 1080px. This provides precise metric measurements from responsive units.
Conversion Formula
mm = (vh × viewport height ÷ 100 × 25.4) ÷ 96
For example, to convert 10vh to mm on a 1080px viewport, calculate (10 × 1080 ÷ 100 × 25.4) ÷ 96 ≈ 28.58mm. This translates responsive sizing to precise metric values.

What is VH?
Viewport Height (vh) is a relative CSS unit where 1vh equals 1% of the browser viewport's height. Like VW, it responds dynamically to viewport changes, making it perfect for full-height sections and responsive vertical spacing. VH units are commonly used for hero sections, modals, and mobile-first designs that need to adapt to various screen heights.
What is MM?
Millimeters (mm) are an absolute CSS unit representing physical millimeters, primarily used for precise print measurements. In web contexts, 1mm equals approximately 3.78 pixels. Millimeters are most useful in print stylesheets and international design contexts where metric precision is required.
