"How It's Made" (Science channel) was showing thick cotton yarn being thinned down for weaving. "Depending on its purpose, this stage 3 yarn is 3½ to 16 times thinner than stage 2 yarn."
What does it mean to make something 16 times thinner? 16 times what?

Think in terms of mm
It could be 3.2 mm at stage 2 and then at stage 3 it would be .2mm
So stage2 * 1/16 = stage 3. Make sense?
Hope that helps.

The yarn has a circular cross section so its thickness would be its diameter. If the diameter of one piece of yarn is 16mm then a piece of yarn with diameter 1 mm would be 16 times thinner.

If you made something 16 times thicker, you would multiply the thickness by 16
So thinner implies division

Thk(stage3) = 1/16 (Thk(stage2)
