The page actually has several different calculators (mm to mm, ratio to ratio, and ratio to mm), instructions for how they work, and a model scale size chart to help if you aren’t sure what scale you’re starting or ending with. Look for your start and end sizes on the chart, then plug that information into the calculator.
