Hi there
I know it is possible to obtain a conversion label from Mph to Kmph for Smiths Speedometer, I hope that this label is in the possession of The MG Experiences Club.
Best regards

Glad you got your answer so quickly John, in 6 minutes no less!

Did you add the thumbs-up to your Original Post title after Barrie gave you his input?

I really like that if you did, it serves as a thank you to (other) respondents and also informs other that your particular problem/query has been solved.thumbs up

Welcome aboard, although you may wish to check out the MGA site for more specific information to your car.

I used a GPS to create my own. I found that the available conversion charts did not match up to the GPS.

Prior to GPS days when we lived in the UK, and often visited France , I wrote the speeds on small sticky labels, and stuck them around the speedo chrome bezel. That made me aware of the speed that I was going in KPH

I'm the guy who actually redrew the sticker. The previous one was a bit dicey and appeared not to be for a MGB. Anyway I did a direct conversion from MPH to KPH and printed and assembled it. Car wasn't running at that stage so I had no real way of testing. However, when I posted my results here and from the corner recesses of my brain I came to the conclusion is was still wrong. So after a minor adjustment I drew and printed the one which is presently in the library.
I reckoned that when the time came and I was able to test the speedo if it wasn't correct I could simply redraw an adjusted version and go with that.
As it turned out checking with a GPS (when my speedo functions correctly - sometimes it doesn't) it was almost spot-on --- for my car.

I just printed it on my HP laserjet using a slightly heavier paper, cut it out and used some spray adhesive to attach it. 12 years later and it still looks fine.

Oh BTW, the suggestion for the % print was found by trial and error and I would suggest you fiddle with that yourself for your printer.

A few others have done redraws again to suit themselves and maybe a search could find them. I deliberated over the numbering and settled on what you see even though I did think it was a bit crowded.

The secret to creativity is knowing how to hide your sources.

To the intelligent person, life appears infinitely mysterious, but the stupid have an answer for everything.
