F/nf stands for

Explanation:
In PCM air sampling, you count fibers across a number of microscope fields and then average those counts. F/nf is exactly the average number of fibers per field—fibers counted divided by the number of fields examined. This standardizes the count so results are comparable even if the number of fields scanned varies. It’s a step used to move toward an estimate of fiber concentration later, but by itself it represents fibers per field, not fibers per area, per cubic centimeter, or total air volume.
