For anything construction-scale, all supplies sold in the US are based on 4x8' sheet goods and 16-24" on-center framing. I also concede that king George the 74th's foot length is more human-scale when dealing with large measurements: 20 feet vs 6096 mm. I still use metric when possible, however - I find it easier and more accurate.
For EVERYTHING else I've switched to using metric.
Context: I grew up in the US using imperial units and only pivoted to the metric system in 2020. If I grew up thinking in metric and building supplies/standards used it, it'd be superior in every way.
TL;DR I like my imperial/metric combo tape measure.
I get angry when hardware uses imperial units because I can't use my metric tools, which are way the fuck easier. Who wants to use 5/8" when you can use 16?
All plans use mm exclusively. Airport blueprints, for example, are in mm. At first blush it seems excessive, but it makes sense from a consistency & accuracy POV - 6.096m takes up 2 more characters than 6096 - they don't even need to specify the units "mm", because it is assumed, and anything else introduces room for error.
