NOTE:
Tables such as Table II, IIA, VIII, and IX may be used as in the following example:
Example: Convert 975 psi to kilopascals (kPa).
1. Select Table VIII.
2. Go to PSI row 90, column 7; read 668.8
97 psi = 668.8 kPa.
3. Multiply by 10:
970 psi = 6688 kPa.

4. Go to PSI row 0, column 5; read 34.47
5 psi = 34.47 kPa. Add to step 3.
5. 970 + 5 psi = 6688 + 34 = 6722 kPa.
975 psi = 6722 kPa.
