These intraconversion tables are applicable to all crude oils, petroleum products, and petrochemicals. These standards are intended for application to bulk liquid quantities. Part 1--Conversions of API Gravity at 60°F

Provides implementation procedures for conversion of API gravity at 60°F to equivalent densities in both in vacuo and in air values. This standard gives the following equivalents for any value of API gravity at 60°F:

  • relative density at 60°F (old Table 3);
  • absolute density at 60°F;
  • absolute density at 15°C (old Table 3);
  • pounds per U.S. gallon at 60°F in vacuo and in air (old Table 8);
  • U.S. gallons per pound at 60°F in vacuo and in air (old Table 8);
  • short tons per 1000 U.S. gallons at 60°F in vacuo and in air (old Table 9);
  • U.S. gallons per short ton at 60°F in vacuo and in air (old Table 10);
  • short tons per barrel at 60°F in vacuo and in air (old Table 9);
  • barrels per short ton at 60°F in vacuo and in air (old Table 10);
  • long tons per 1000 U.S. gallons at 60°F in vacuo and in air (old Table 11);
  • U.S. gallons per long ton at 60°F in vacuo and in air (old Table 12);
  • long tons per barrel at 60°F in vacuo and in air (old Table 11);
  • barrels per long ton at 60°F in vacuo and in air (old Table 12);
  • metric tons per 1000 U.S. gallons at 60°F in vacuo and in air (old Table 13);
  • metric tons per barrel at 60°F in vacuo and in air (old Table 13);
  • barrels per metric ton at 60°F in vacuo and in air;
  • cubic meters per short ton at 15°C in vacuo and in air (old Table 14);
  • cubic meters per long ton at 15°C in vacuo and in air (old Table 14).


While not related to API gravity, the following are included for user convenience:

  • U.S. gallons at 60°F to litres at 15°C (old Table 4);
  • barrels at 60°F to litres at 15°C (old Table 4);

Part 2--Conversions for Relative Density (60/60°F)

Provides implementation procedures for conversion of relative density (60/ 60°F) to equivalent densities in both in vacuo and in air values. This standard gives the following equivalents for any value of relative density (60/60°F):

  • API gravity at 60°F (old Table 21);
  • absolute density at 60°F;
  • absolute density at 15°F (old Table 21);
