How to convert SVG coordinates for objectBoundingBox?

Question

SVG

In order to use SVG with you clipPathUnits="objectBoundingBox"need coordinates between 0 and 1.
But Illustrator exports path

<path d="M2.52,22.68C9.15,33.84,17,43.43,25.79,53c2.63,2.84,6.86-1.41,4.24-4.25-8.43-9.13-16-18.35-22.33-29.06-2-3.32-7.16-.3-5.18,3Z"/>

How can I translate this into relative coordinates?
PS: with every minute spent digging into SVG, I get more and more fucked up. People, how do you live with it?
