Mike,
You might wish to look at
http://mutcd.fhwa.dot.gov/ on this matter.

I expect that metric speed limit signs will be given in integer
multiples of 5 km/h. Perhaps existing speed limits given in miles per
hour (mi/h, or "mph") will be either be rounded down or rounded to the
nearest such multiple. For example 55 mi/h might go to 90 km/h or to 85
km/h, but not to 88 km/h.
Distance signs likely will be to the nearest whole kilometer (18 km) or,
for small distances, to the nearest kilomter by tenths (2.7 km). Very
small distances might be in multiples of 100 m. There are several
instances of metric distance signs in the US already, as have been noted
on this forum.

This is a question that is off topic but I've often wondered, when we
finally complete the transition to the metric system how will speed
limits and distances be labeled? Will the be rounded? For instance 35
mph would be 60 km/h but 40 mph would also be 60 km/h, 15 mph would be
20 km/h? Distances, 1 mile is 1.6 km but would this be rounded up to 2
km? Will distances be rounded up or down as needed or will decimals be
in place? I.E.: 1/4 mi 400 m, 1/2 mi 800 m, 3/4 mi 1.2 km or will it be
1 km? I've attached a visual I made so you get the idea
.
