I will guestimate a millionth of a millimeter. Break out the microscope plotter ;-)

Incidentally, this reminded me of something I noticed recently on the US National Weather Service website. If I click on one of the maps to select a "local forecast", it returns the latitude and longitude as lon=-71.38935930175779, lat=41.46786617225138 (example coordinates generated by a click just now). Yes indeed: that's a local forecast! Just how much of a difference in position would change that latitude from 41.46786617225138 to 41.46786617225139... ??
