The following information will be expanded as more is learned...

Not much is known about GHT and where it actually came from, except that it appears so far to be designated in only one size, that being 3/4 inch.  GHT is not compatible with any other thread. Fittings for hose sizes of 1/2", 5/8", and 3/4" are commonly found in U.S. hardware stores.  It is rather unfortunate that GHT didn't follow NPSH, which would allow a garden hose to be screwed onto the end of a 3/4 pipe without requiring an intervening fitting.  Oh well...
