were included in the Sl equivalent if there was any ques tion. The values of allowable stress in Section Il, Part D generally include three significant figures. (e) Minimum thickness and radius values that are ex oressed in fractions of an inch were generally convertec according to thefollowing table:

(g) For nominal pipe sizes, the following relationshi were used:

(h)Areas in square inches (in.)were converted to square millimeters (mm°) and areas in square feet (ft*) were converted to squaremeters (m').See examples in the following table:

(h) Areasin square inches(in.)were converted square millimeters (mm°) and areas in square feet (f were converted to square meters (m").See examples chefollowingtable:

() Volumes in cubic inches (in.3) were converted to cubic millimeters (mm) and volumes in cubic feet (ft*) were converted to cubic meters (m'). See examples in the following table:

()Volumes in cubic inches (in.) were converted to cubic millimeters (mm) and volumes in cubic feet (ft) were converted to cubic meters (m'). See examples in the following table:

calculations,thereare cases where other units are used in che text.For example,kPa is used for small pressures. Also, rounding was to one significant figure (two at the most) in most cases. See examples in the following table. (Note that 14.7psi converts to 101kPa,while15psi converts to 1oo kPa. While this may seem at first glance to be an anomaly,it is consistent with the rounding philosophy.)

(k) Material properties that are expressed in psi or ks e.g., allowable stress, yield and tensile strength, elasti lodulus)were generally converted to MPa to three sig ificant figures. See example in the following table:

() Inmost cases, temperatures (e.g.,for PwHT) were rounded to the nearest 5°C.Depending on the implied precision of the temperature, some were rounded to the nearest 1°C or10°C or even 25°C.Temperatures colder than o°F (negative values) were generally rounded to

the nearest 1°C. The examples in the table below were created by rounding to the nearest 5°C, with one exception:
