Don't scream my American friends, or cover your eyes if you can't bear a discussion on the metric system and don't read further.
Has anyone calculated what the gear tooth would be to get the speedometer needle to read at km rather than miles? As an example my 150 speedometer is reading higher presently because I changed my 8 3/4 gear ratio. I'm expecting my old gear will be a 30 tooth and I need a 32 tooth for the new rearend. But if I were to go less, say 28 tooth then the needle would be closer to kilometres. I'm guessing there is a mathematician out there seeing that its a known difference between the two measurements - 1 km is .62 mi.
I know this would change my odometer calculations but I'm not planning on selling my car based on "low miles" any time in the future. No one would ever know when the car is parked either. This may seem sacrilicious to some but it does make it easier for our streets.
Anyone up for the math test?
Thanks
