If it makes you feel better,  I met two guys from Omaha, NE at the solar 
conference in LA and they, unprompted, started giving me solar power parking 
canopy part lengths in meters! They said,"it's easier"! I thanked them on 
behalf of USMA!

why 2/32?  surely 1/16 would be ?cleaner'

The legal minimum tread depth in Europe is 1.6mm (4mm for winter tyres). It is, 
however, recommended to replace tyres by the time they reach a tread depth of 
2mm. The tread grooves of a tyre contain wear indicators, called TWIs (Tread 
Wear Indicators).

Federal regulations set minimum tread requirements for commercial trucks, the 
states regulate for passenger cars. In both cases the rules are written in 
32nds of an inch. The brake lining specs are probably from the manufacturer. It 
probably makes sense to measure in the same units as applicable rules.

Commercial trucks: 4/32 on the steerable wheels, 2/32 on all other tires
Passenger cars: Some states may vary but generally 2/32 on all tires.

I took my Honda CR-V in for routine maintenance today. The printed report show 
depth of brake linings in millimeters and depth of tire treads in 32nds of an 
inch (0.8 mm).   sigh   And one of those measurements was for 6.5, so that half 
of 1/32 inch meant their instruments were capable of measuring down to 1/64 of 
an inch (0.4 mm). Why not just do everything in half millimeters? There?s 
probably no way they could justify that level of precision in any case.
