Oddly specific distances on signs

[BigRTM]

I-275 NB to Dale Mary Hwy in Tampa. 2/10 Mile.



This sign is now gone after the recent renovation and expansion of I-275.

This sign in Perth gives you the distances down to the nearest 100m. Also some interesting use of '&' to group exits together:

For some reason, there are several advance height clearance warning signs on US 95 in northwest Las Vegas that are placed at oddly-specific distances.

Examples, via StreetView:
US 95 SB approaching Exit 81 Summerlin Pkwy & Rainbow Blvd (SR 595) - 15'-7" height clearance warning 6,390 feet ahead
US 95 NB approaching Exit 90A Rancho Dr (SR 599/US 95 Business) - 15'-3" height clearance warning 2,860 feet ahead

These are not distances that anybody would easily parse for a driving distance, especially on a freeway. What's even more interesting is that they end up being an awkward number when converted to miles (1.21022727272... or 0.5416666... miles, respectively).
