You have no idea how hard it is to get Americans to use 100% metric everything, even in the year 2016 in a highly technical field. It's incredibly frustrating. I'm amazed at the number of people under age 30 who have clearly not been taught even the basics of the metric system in middle school and high school, or intentionally disregarded/forgot it.
Working in the US domestic economy is unavoidable to do many things in US customary units when construction/physical engineering of things is involved. For example if building mission critical telecommunications towers to EIA/TIA 222G standards, everything is going to be in US customary units (the tower structure itself, the fasteners, the guy cables, the anchors, the foundation/concrete job, the dimensions of the equipment shelter, the electrical conduit, etc).
