kilometres to mph

Cheers guys Oxygen im going to buy the speed healer thanks for the link to the site etc.  When I need a new chain and sprocket im going to go one down at the front and one up at the back (I think thats right) :rollin to get a little more economy when in 6th gear with all the petrol price increases i think its worth the change. A few of us went to Betws y coed llanberris snowdon etc last night and we werent hanging about  :car and I got 57mpg so not to bad. Can anybody reccomend a good sprocket chain kit thanks Kazz  .
