n: ten times the newton, which is the unit of force in the metric system.

n pi: 1. value that indicates hook load or force, read from a weight indicator;1 point = 1,000 pounds, or 500 decanewtons. 2. in mud density measurement, the portion of the muds weight expressed in decimal points. For example, a mud that weighs 12.2 pounds per gallon (1,461.8 kilograms per cubic metre) weighs two points more than 12 pounds ( 1,438 kilograms). Also, if a 12.2 potmd-per-gallon muds density is increased to 12.5 pounds per gallon (1,497.8 kilograms per cubic metre),the density has been raised by 3 points.
