Accidentally deleted unit preset inches and feet

I was exploring some unit measurements in Blender 2.79’s scene area and I accidentally deleted the inches and feet Unit Presets. Does anyone know how to get that back without going into a factory restore?

Unit Length Presets are stored as .py files in /blender/2.79/scripts/presets/units_length/

I guess a solution for you would be to make a factory reset in another temporary directory, and copy missing .py files…


Thanks I actually found the answer and that was looking up the actual unit scale for an inch and foot and put it in as a new entry. Just found it yesterday.
