Fly Fishing Tippet Conversion

Tippet Rule of Thumb:
Divide the hook size by 4 to get the “X” designation.
Example:
#12 Hook divide by 4 = 3X Tippet
#16 Hook divide by 4 = 4X Tippet

Tippet conversion:
The base diameter for tippet is .011″ which is 0X. For each .001″ diameter smaller than the base diameter add 1 to the “X” designation. “X” stands for times smaller than the base diameter. So 3X (.009″) is 3 times smaller than the base diameter 0X (.011″).
