Yes, everyone knows metric is nicer. But it’s just not an issue at all in day to day life. How often do you need to know the weight of a certain volume of water or the edge length of a cube that exactly contains that much water? For temperatures, everyone memorizes 32 and 212 as a small child and never had to worry about looking it up.
Would I rather use metric? Sure. But when almost everything is labeled in US units, all the advantages of metric pale in comparison to the hassle of having to convert almost every single measurement I encounter.
