Greetings all brand new collector here
Advice from another dumb engineer but why not just get a small ruler with metric on one side and US standard on other and use it? Or as a second idea get a small flat piece of wood that is rectangular, measure out cm notches on it and paint it alternately black and white?
Personnally I would go with the ruler, but I am just another high IQ, low common sense engineer (as my wife tells me).
