thanks for pointing out it's a round speedo .. I should read the question always. Change my word "trip " to "odometer"or "mileometer" to bring it into line! ...yes when touring europe I always estimate at kms miles at 2/3... I find the sum easier than 5/8- sure, not accurate but quicker in my head.... in my model As the mileometer have seldom worked anyway ... I always fit a bicycle speedo now... BUT in true Fordbarn style we have strayed completey from what the OP #1 wanted to know.... he wanted to know if poss to convert thespeedo .. not arithmetic or other options ....
