The poundal , pdl for short, is a non- SI -conforming unit of force . It is part of the Anglo-American absolute foot-pound-second system of measurement , a coherent sub-system of English units introduced in 1879.

It is defined as 1 pdl. = 1 lb · ft · s ^-2 .

Thus, for the conversion into the SI: 1 pdl applies. = 0.138 254 954 376 N .
