To calculate the depth of a thread, measure the distance from the crest (top) to the root (bottom) of the thread. This can be done using a thread gauge or caliper. The depth can also be determined by subtracting the root diameter from the major diameter and dividing the result by 2, as thread depth is half the difference between these two diameters. For standard threads, the depth can be found using specific formulas based on the thread profile, such as for triangular threads.
A PTF thread is the same as a NPT thread except that it has one thread less at the small diameter end. It is used when there are space (depth) considerations.

A device to measure the tire's thread depth.
It's the depth of the cut from the crest of the surface down to the base on a bolt or screw.

The equation to calculate water depth is: [ Water Depth = Volume of Water / Surface Area of Water ]
You measure it. If you want to calculate it, please clarify what information you have available.
Thread size of bolts is calculated by measuring the depth, width, and length of the threads. This helps to identify specific bolts and patterns.
Real depth Dr= Apparent depth/ refractive index of water Dr= Da / n water
The common values needed to determine the travel distance of a thread are the thread pitch (distance between threads), the number of turns or rotations made by the thread, and the diameter of the thread spool. By knowing these values, you can calculate the total distance the thread travels when wound or unwound.

The Legal minimum thread depth is 2/32". But should be replaced if under 4/32" in spite of the legal minimums.
