Enter the table in the column "API Gravity at 60oF, headed 64o API, and note that against an "Observed Temperature of 34oF" the factor is 1.0168
Likewise, from the column headed 65o API, note that for the observed temperature of 34oF the factor is 1.0170
This represents an increase of 0.0002 in the factor for an increase of 1.0o API. Therefore, by simple proportion, an increase in gravity from 64.0 to 64.80o API increases the factor by 0.8 x 0.0002 or 0.0002
Then, one U.S. gallon of oil having a gravity of 64.80o API at 60oF and measured at 34oF occupies at 60oF a volume of 1.0168 + 0.0002 or 1.0170 U.S. Gallons
Therefore, 10,000 U.S. gallons measured at 34oF occupy at 60oF a volume of 10,000 x 1.0170 or 10,170 U.S. Gallons
