Introduction - Section 1 OM1012.2 Page 1-12 Standard Charts and Tables 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. 4. Go to PSI row 0 , column 5 ; read 34.47 5 psi = 34.47 kPa. Add to step 3. 2. Go to PSI row 90 , column 7 ; read 668.8 97 psi = 668.8 kPa. 5. 970 + 5 psi = 6688 + 34 = 6722 kPa. 975 psi = 6722 kPa. 3. Multiply by 10: 970 psi = 6688 kPa.
