MM to VH Converter
Use this free online mm to vh converter tool to convert millimeters to viewport height units. Millimeters are a metric measurement while VH is a responsive web unit. This converter helps translate precise metric measurements to responsive vertical layouts.
To convert millimeters to vh, divide by 25.4 to get inches, multiply by 96 to get pixels, then divide by viewport height and multiply by 100. The default viewport height is 1080px.
Conversion Formula
vh = (mm ÷ 25.4 × 96 ÷ viewport height) × 100
For example, to convert 25.4mm to vh on a 1080px viewport, calculate (25.4 ÷ 25.4 × 96 ÷ 1080) × 100 = 8.89vh. This means 25.4mm (1 inch) equals approximately 8.89vh at this viewport size.

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.
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.
