Just out of sheer curiosity....What is that one from?

I may try to create an overlay - some vinyl graphics might work well. I'll have to see if I can find a speedo in a junkyard here that I can rip apart to measure for the radius.


This one was in a 75 series pickup and I have also seen them in Troopys. Many trucks sold in the Americas have the MPH gauges, and in several parts of the Europe. I also encountered a couple in Ethiopia with MPH gauges as well.
 
You can practice your "times 6 tables", 60 kph x 6 = 36 mph. Not 100% but close.

I just got an app for my phone that uses GPS to calculate speed. Works good and I don't have to practice my math or think about larger tires adding 6% more speed that doesn't show up on the speedometer.

There are several free apps that track speed and miles.

100%

The app I use also can be ran in kph, so I can verify the speedo. 😉

Not sure if you use your Inclinometer or not, but if not, that is a great space for a 60mm GPS Speedometer.
They are compact and fit easily in the stock housing, along with EGT and Boost Gauge. Hole saw cost about as much as the 60mm GPS Gauge. They boot up fast, are accurate, and they seem to hold up well. If you travel up to Canada or down to Mexico just push the button and back to KMPHs. Glad I pulled the trigger on that item.

 
I use Math to get USA speed. With my 33” tires the ratio is almost exactly 2/3.
I used a phone app to figure this out.
