@fluffy Come within 3 Dachshunds of me and say that! XD

But no, Americans use metric all the time. Just for smaller-scale things, mostly. A meter and a yard are so close we just use yards and kilometers are less used than miles, but every socket set you can buy comes with metric, every ruler or measuring stick, and we even use 1L bottles when a pint is almost exactly the same.

People give you side-eye if you start talking about mass, though, since that's used pretty much exclusively for drugs, prescribed or otherwise. Yes, even kilos.
