Do You Know – Smallest unit in KiCAD is 1 nm

Smallest unit in KiCAD is 1 nm. This is (1/1 000 000)-th of millimeter.

Do-You-Know

Quite precise for PCB design. For comparison the popular Eagle CAD base unit is 1 um which is 1000 times bigger, so KiCAD uses 1000 times more precise metrics than Eagle.
