Google tire conversion chart. Use it. Enterthe metric measurements. It will convert it to inches.

Don't forget to take off 3-5% for "squish" factor.

do the chalk test, you will get the most accurate measurement that way. I did mine that way and my speedo is 1 mph an hour slower than a cops radar

Measure from the center of the hub to the ground and double that.
