(Multiply in by 25.4 to obtain mm.)
(Multiply lbf/ft2 by 0.04788 to obtain kN/m2 (kPa).)
awall A thickness in inches = diameter in feet; wall B thickness in inches = diameter in feet + 1 in; wall C thickness in inches = diameter
bAlthough not specifically called out in ASTM C76, 8 in and 10 in diameter circular concrete pipes are routinely manufactured.
