Work out equivalent CBR from Plate Load test

I've seen some things through google, but can't seem to get the right result.

We have had some plate load tests done, but client wants to have the CBR equivalent result and well.

Maximum load applied to plate was 570, with 1.26mm settlement in the ground, and using a 300mm plate.

How would I calculate the CBR from these figures? Or do I need something else as well?

Many thanks
