KPA into LB's or Bar?

Ok, so my buddy just picked up a Greddy Profec for his Subaru Impreza STi. The thing is, from what he’s telling with the Profec, boost is measured in terms of KpA instead of Bar or Lb’s. He asked me how to convert it but I have no idea. Since I know there are some really smart guys in here, I was wondering if maybe you guys could help me out. Like what would be the KpA of 1lb?

Thanks guys. .
