Imperial measurements are typically based off of something in the real world that makes sense in context. A foot is about the size of your foot, an inch, is roughly the size of one of your finger segments.
Of course you bust out the ruler for precise measurements, but like 80% of work is just estimating sizes until you cut down to a precise size so having an intuitive grasp on measurements can save a lot of time.
Metric measurements are based on some arbitrary constant to have consistency for scientific and engineering purposes. Like who the fuck is going to intuitively know the distance light travels in 30.66 radiation transitions of the cesium atom?
Sure, you can get a feel of metric sizes if you grew up using metric units, but it will still never be as intuitive as imperial measurements on smaller scales.
