The Imperial System's Tire-some Explanation

The imperial system strikes again! While the metric side calmly states "2 Bar = exceeds atmospheric pressure by twice the pressure of the atmosphere," the imperial side goes full medieval manuscript with "29 PSI = exceeds atmospheric pressure by 29 times the weight of 7,000 grains of wheat spread over a square area the length of three grains of sound ripe barley being taken out the middle of the ear, well dried, and laid end to end in a row." This is why scientists worldwide collectively facepalm when dealing with unit conversions. The absurd complexity of imperial measurements makes rocket science look like counting fingers. Next time someone asks why we need the metric system, just show them this tire.
