Your method of calculation sounds correct. I am wondering if the cycle computers can cope with the 'unusual' tyre size?

I'm thinking of fitting my Sat Nav in my bike

I won't get lost and I can see the speed I'm doing.

Trouble is, can't figure out how to fit it in handle bar

Not uncommon these days. Garmon and the like are popular brands to use.
