Units and fractions

MillPath starts in inches where your browser’s language is US or Canadian English, and in millimetres elsewhere. The mm / inch switch in the top bar changes it, and MillPath remembers your choice.

Length fields take decimals (12.5, or 12,5) and fractions the way inch measures are written: 3/4, 1 1/2, 1-1/2, with or without " or in.

The G-code file says its units (G20 / G21; a units guard in ShopBot files), so the controller follows the file.
