Hopefully some of you will know this off hand - especially some of the folks who work internationally. Here’s my question: What are the sprinkler sizes used in countries outside the U.S. where the metric system is in place? Here we use ½” NPT, ¾” NPT, etc. I know the literal conversions - i.e. ½” = 12.7 mm - but is that what the sprinklers are sold in? Thank you in advance for any help that can be provided.
