The number you're entering into the computer is the circumference in cm. I always measure out the circumference of any wheel, even if the circumference is specified in the manual for a given wheelsize because tires vary in height. Just roll your bike for one revolution and measure the distance with a tape measure and convert to cm.

Ya know, I know that was meant as tongue-in-cheek but it's a damned good point: after I don't know how many years of making nearly all of my "garage" measurements in metric, I still have yet to buy myself a metric tape. :skep:
To be truly accurate you should 'rollout' aand measure the front tyre with some weight on it as a tyre with weight on it ie. when riding will have a different rolling measurement than an unweighted tyre
