Speedometer Gear for Km?

Thanks for your input guys. I did not want to change the faceplate on the speedometer. I was looking at the gear change only and already knew my 32 tooth gear to keep it at a MPH speedometer. I believe 69_340_GTS is correct in that I need to either divide my existing gear (32 tooth) by 1.609 or multiply by .62 . The answer is at 21 tooth which is non-existent. The lowest is 24 tooth and that won't work unless I install some whopping big tires on the rear!! Thanks again, I'll stick to the MPH and tell my son that 60 kph is NOT the same as 60 mph!

On an interesting note. While searching this stuff I found my 215/70R14 tires are equivalent to a 7.75 x 14 tire (vintage tire size 1965-72) My 69 Service Manual lists a 7.75 x 14 tire with 3:23 diff as having a 32 tooth speedometer pinion for that combination. However all of the charts on the web, and this site, suggest a 215/70R14 tire (26") with a 3:23 diff requires a 33 tooth speedometer pinion. I'm going with the Service Manual recommendation.
