The design is in millimeters for the most part, but some things like bolts, nuts and threaded rods are in inches.
If, like me, you're not familiar with them, inch fractions are quite unreadable... So I made a table to (hopefully) reduce the number of errors I will make.
The mm + x" columns are included to make looking up lengths like 2 3/8" a bit easier.
