The imperial system has a great UX and is as precise as metric so there's no real incentive to change. For science metric makes a lot of sense of course and we use it there (mainly!) and we use it for trade, but for day-to-day use among people, why change? It's very intuitive in terms of unit sizes being very much at human scale. Even when doing woodworking/carpentry, the imperial system is really nice being based on 12 in many aspects. The foot/inch system is great for day to day use. The centimeter is too small and the meter too large, for example. I also think it's nice that different countries do things differently. It gives you identity and makes the world a more diverse and interesting place. I love that the UK has measurements like "stone" when describing a person's weight and that they use miles per hour for driving and kilograms for buying food and drive on the left side of the road.
