Why do you think we don’t work in metric? I use it all the time. It’s a lot easier to calculate the center of a 200 mm part…as opposed to the center of one that is 7 7/8". Or if I want to divide another part into 4 pieces. Let’s see…100 mm…or 3 15/16"? Which should I choose?
Sheesh Bruce 
You’re giving away all the “secrets” that are hidden in the metric decimal system. :lol: Which reminds me: This from last year’s “Uncle John’s Bathroom Reader Calendar”

An Absorbing Question Why are there 5280 feet in one mile? When the Roman Empire ruled Britain (from the 1st to 5th century AD) they had a measurement known as a milia pasuum (“thousands of paces”), which roughly equaled 5’000 feet. When the Roman Empire fell, the British kept that “mile” but eventually changed its length because they wanted to combine it with the “furlong”, a land measure of 660 feet. They wanted to make 8 furlongs equal 1 mile, and that made the mile 5280 feet, not the traditional 5’000. So why choose the odd length? Because a shorter mile would have meant a smaller measure of land - and landowners weren’t about to let that happen. So the mile became 5280 feet long.
What has any of this to do with model railroading? Hmmmm … let’s see i.e. 3.5mm/12"; a perfectly “logical” mixture of two systems of measurements to suit “whatever”, “whoever” at the time of inception! :lol: :lol: But why not, it is a time honoured tradition going back many centuries!
