MM to PX Converter
Use this free online mm to px converter tool to convert millimeters to pixels. Millimeters are a precise metric unit while pixels are the standard web unit. This converter bridges precise metric measurements with screen-based designs.
To convert millimeters to pixels, multiply by 96 and divide by 25.4 (since 1 inch equals 96 pixels and 25.4 millimeters). This follows the CSS specification for absolute unit relationships.
Conversion Formula
px = (mm × 96) ÷ 25.4
For example, to convert 25.4mm to pixels, calculate (25.4 × 96) ÷ 25.4 = 96px. Similarly, 1mm equals approximately 3.78px because (1 × 96) ÷ 25.4 ≈ 3.78.

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 PX?
Pixels (px) are an absolute CSS unit representing a single dot on screen, normatively defined as 1/96th of an inch. They are commonly used for precise element sizing in web design. However, pixels can create accessibility issues as they don't scale with user browser preferences, making them less ideal for responsive typography.
