The core imperial / standard units really are not that weird. Sure not as neat and tidy as metric with its base 10, but really not hard to work with.
Most of the really out there units are very industry specific, hogsheads, bushels, ffurlongs etc, and they are only weird out of context. If you were a 19th century winemaker then Horseheads would seem perfectly reasonable.
Metric is less flexible resulting in its own need to adapt non-metric units in specific cases such as the French system for medical catheters or gauge system for needles.
Don't even get me started on Celsius which in no way follows the rule of 10 of the metric system and is just as arbitrary as ferenheit only using other numbers.
