English: A diagram of a Unified Standard Thread

${\displaystyle Pitch=1/TeethPerInch}$ ${\displaystyle H=0.866025*P}$ ${\displaystyle H1=0.541266*P}$ ${\displaystyle d2=dimeter-1.082532*P}$ ${\displaystyle d1=dimeter=1.082532*P}$ ${\displaystyle D=d}$ ${\displaystyle D1=d1}$ ${\displaystyle D2=d2}$

This image is superior and equivalent, but requires descriptions using d, d1, and d2 to use D_min, _maj, _P respectively.
