SS Rope sizing questions

[ScottP]

So I am getting ready to order some SS rope and a thought occurred to me, how accurate is the sizing? I know that when you go buy a 2x4 board it is really only 1.5x3.5 or so. They just round up to the nearest whole inch.

So if I buy a 3/32 SS rope is it exactly 3/32 (2.38mm) or is it really 2mm converted to the nearest fraction? If I buy 2mm is it really 2mm exactly or is it 3/32 rounded down to the nearest mm? Is 2mm and 3/32 in fact the exact same size or are they really different?

The same could be asked of 1/16 (1.59mm) and the 1.5mm SS ropes. Same or actually different?

If no one knows, all we need is for a couple of people with dual unit calipers to measure some SS rope in both units. One person can measure some SAE rope in both units and someone else can measure some metric rope in both units.
