TABLE 110. — Specific Gravities Corresponding to the Baume Scale 



The specific gravities are for i5.56°C (6o°F.) referred to water at the same temperature 

 as unity. For specific gravities less than unity the values are calculated from the formula : 



140 



Degrees Baume = 



For specific gravities greater than unity from:

TABLE 111. Degrees A. P. I. Corresponding to Specific Gravities at 60°/60° F. 



(i5.56°/i5.56° C) for petroleum oils. 

 In order to avoid confusion and misunderstanding the American Petroleum Institute, 



the 



Bureau of Mines, and the Bureau of Standards have agreed that a scale based on the modulus 

 141. 5 shall be used in the United States Petroleum Industry and shall be known as the A. P. I. 

 scale. The United States Baume scale based on the modulus 140 will continue to be used for other 

 liquids lighter than water. 



Calculated from the formula, degrees A. P. I. = ^ — ~ — , ' . — 131.5
