the imperial and metric systems serve different purposes and trying to shoehorn all jobs into one is a recipe for disaster. the metric system is about scientific, replicatable precision. the imperial system is about quick, rough estimate measurements using the one thing you always have available, your body. you use the metric system when building a rocket. you use the imperial system when estimating how much mulch to buy for your garden of if a throw rug will fit in a room.
