25.4 is all you need to know. To convert inches to millimeters take the inches measurement (let’s say 1.5 inches) and multiply it by 25.4 (1.5 inches x 25.4 = 38.1 mm)

To convert mm to inches simply reverse the formula, take your mm measurement (let’s say 12.7mm) and divide by 25.4 (12.7 mm divided by 25.4 = .5 inches or 1/2”.

Also, when you’re doing this you need the decimal equivalent for your calculations. Most drawings will be in fractions. 1/4”, 1/2”, 3/4” are easy, (.25,.5,.75) and all you need to do for the trickier ones is divide the fraction. 9/16” would be 9 divided by 16 = .5625

Hope that helps, and makes sense, and doesn’t just sound like the ramblings of a crazy person : )
