oops.... Jeff is the igmo
pounds of air is weight
pounds per square inch is pressure
Jeff’s usage is incorrect because he is ignorant on the subject
People use “pounds” to denote pounds per square inch all the time.
When I pulled in to the pits during an endurance race I did not tell my tire guy “Please inflate the rear tire by an additional 1.5 pounds per square inch of pressure” - I yelled “Add 1.5 pounds to the rear”. He knew what I meant, and I avoided spending half the day on pit road.
The article even included the notation “(PSI)” at the end of the sentence in question.
Jeff may very well be ignorant, but your misguided criticism is not proof of such.
