Pitch diameter British thread Solution

Follow our step by step solution on how to calculate Pitch diameter British thread?

FIRST Step Consider the formula

D = M - 3.4829 \cdot G + 1.13634 \cdot P

Next Step Substitute values of Variables

∴

D = 8.2mm - 3.4829 \cdot 1.2mm + 1.13634 \cdot 3mm

Next Step Convert Units

∴

D = 0.0082m - 3.4829 \cdot 0.0012m + 1.13634 \cdot 0.003m

Next Step Prepare to Evaluate

∴

D = 0.0082 - 3.4829 \cdot 0.0012 + 1.13634 \cdot 0.003

Next Step Evaluate

∴

D = 0.00742954m

Next Step Convert to Output's Unit

∴

D = 7.42954mm

LAST Step Rounding Answer

∴

D = 7.4295mm
