Architects for example almost exclusively work in feet in the US. The US construction field is almost entirely imperial.
The highest rates of metric use in the US are in cases where there is a possibility of international crossing/exchange, or if the field is distinctly metric-based. If you work for NASA, it makes sense to use global measurement standards. If you're building a house in Cincinnati, it largely does not matter.
If you're a German working in a store in Würzburg, you're far more likely to speak in German throughout your day. If you're a German working in programming with a bunch of US programmers, you're more likely to be using English when communicating with them. Why don't Germans speak English all the time? Because they don't want to and don't need to.
