Pitch diameter British thread Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pitch Diameter = Micrometer Reading-3.4829*Wire Diameter+1.13634*Screw Pitch
D = M-3.4829*G+1.13634*P
This formula uses 4 Variables

Variables Used

Pitch Diameter - (Measured in Meter) - Pitch Diameter is the diameter of the basic cylindrical shape on which threads are created.
Micrometer Reading - (Measured in Meter) - Micrometer Reading is the reading of an instrument which can measure thickness of very small objects.
Wire Diameter - (Measured in Meter) - Wire Diameter is the diameter of the wire in thread measurements.
Screw Pitch - (Measured in Meter) - Screw Pitch is the distance between screw threads and is commonly used with inch sized products and specified as threads per inch.

STEP 1: Convert Input(s) to Base Unit

Micrometer Reading: 8.2 Millimeter --> 0.0082 Meter (Check conversion here)
Wire Diameter: 1.2 Millimeter --> 0.0012 Meter (Check conversion here)
Screw Pitch: 3 Millimeter --> 0.003 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D = M-3.4829*G+1.13634*P --> 0.0082-3.4829*0.0012+1.13634*0.003

Evaluating ... ...

D = 0.00742954

STEP 3: Convert Result to Output's Unit

0.00742954 Meter -->7.42954 Millimeter (Check conversion here)

FINAL ANSWER

7.42954 Millimeter <-- Pitch Diameter

(Calculation completed in 00.004 seconds)

What is the use of Three wire method ?

The accurate measurement of thread pitch diameter, which may be perfect as to form and lead, presents certain difficulties which result in some uncertainty as to its true value. The adoption of a standard uniform practice in making such measurements is, therefore, desirable in order to reduce such uncertainty of measurement to a minimum. The “three-wire method” of measuring thread pitch diameter, has been found to be the most generally satisfactory method when properly carried out, and is recommended for universal use in the direct measurement of thread plug and thread setting plug gauges.

How to Calculate Pitch diameter British thread?

Pitch diameter British thread calculator uses Pitch Diameter = Micrometer Reading-3.4829*Wire Diameter+1.13634*Screw Pitch to calculate the Pitch Diameter, The Pitch diameter British Thread formula is defined as the diameter where the thread thickness is equal to the space between the threads. Pitch Diameter is denoted by D symbol.
