How to Evaluate Pitch diameter whitworth?

Pitch diameter whitworth evaluator uses Pitch Diameter = Micrometer Reading-3.16568*Wire Diameter+0.96049*Screw Pitch to evaluate the Pitch Diameter, The Pitch Diameter Whitworth formula is defined as the diameter of an imaginary cylinder that intersects the thread profile at the point where the width of the threads and the width of the spaces between the threads are equal. This measurement is fundamental for determining the effective size of the thread where proper engagement and functional fit occur. Pitch Diameter is denoted by D symbol.
