A resident of that land to the west of the Atlantic told me that the 'old 3 4 5 right angled triangle setting out trick' didn't work in SI units. I assured him that it would, and that setting it out with Cornflake packets would work too.
If he were just a little brighter he'd have told me that Kellogg's is Murican.
