Display SVG with mm measures in browser with real life size

I have a SVG image that I would need to display in real life size. Currently my paths are already defined in mm like this :

 <svg xmlns="http://www.w3.org/2000/svg" xmlns:lc="http://www.librecad.org" xmlns:xlink="http://www.w3.org/1999/xlink" width="1480.64944013mm" height="276.99494955mm" viewBox="0 0 1480.64944013 276.99494955">
<g lc:layername="0" lc:is_locked="false" lc:is_construction="false" fill="none" stroke="black" stroke-width="1">
    <path d="M1424.59844281,29.19495985 L0,29.19495985 L0,276.99494955 L1424.59844281,276.99494955 L1424.59844281,29.19495985 Z "/>
    <line x1="250.93711729" y1="206.68428137" x2="251.81394846" y2="209.84892956"/>

Can someone just give me some clue or direction on how can this be displayed on my browser in real mm ? That can be measured with a ruler
