On the main page, click on "Basketball Rules". (The source I quoted in my previous message on this topic was about basketball EQUIPMENT, which includes baskets and backboards and such, but not the layout of marking on the floor. BOTH equipment AND floor markings are included in the "Rules".)
The specified court size in the rules was of some concern to me. It is given in these rules as: length 28 m, width 15 m (for all main official competitions and all new construction, minimums for other competitions are 26 m and 14 m.) There would seem to be a discrepancy between this and what I previously reported; namely, length 32000 mm (32 m) and width 19000 mm (19 m). I think those larger measurements were for the entire floor, not just the playing surface; i.e. they included the space for the scorers' tables and team benches, etc.
Here are some of the other interesting sizes specified in the rules, all purely in metric:
Height to ceiling (or lowest obstruction): 7 m
Free throw line: 5.80 m from end line
3.60 m long (centered)
Location of basket (center): 1.575 m from end line
Center circle: radius 1.80 m
3 point circle: radius 6.25 m from center of basket
There was a diagram of the free throw lane which is a complex shape; it showed all dimensions in metres and centimetres. I won't try to repeat all those various dimensions here.
It does seem that on the international level, basketball is metric, even in spite of the possibility that a few of the dimensions are metricated versions of old feet or inch measurements.
