Kip :: In the English system, we use pounds to describe weight and feet or inches to describe distance. You may remember that 2000 pounds is called a "ton", but did you know that 1000 pounds is called a "kip"? (It was most likely shortened from "Kilo-Pound") So, when you see a notation like "kpf", think "kips per foot". 0.48 kpf would be equal to 480 pounds per foot. Engineers use kips since it makes the numbers much easier to work with (especially in the days of slide rules) and reduces errors caused by lost zeros.
