You could also do a "cheat sheet" in Excel, and use large type so you can read it from afar?
I have one of these in my workshop for my calipers to convert from inches to mm's, and fractions of an inch to decimals of an inch.
I first did this for my wife 15 years ago when we lived in Tunisia and her cooker scale was in degrees Celcius, but she could only think in Fahrenheit.
