Density (at T) = Density (at 60°F) × CF
ASTM Table 54B is a standard table used in the petroleum industry to calculate the density of crude oils. Here is a useful paper on creating an Excel spreadsheet to work with ASTM Table 54B: Astm Table 54b Excel
where A, B, and C are coefficients from ASTM Table 54B, and T is the temperature in °F. Density (at T) = Density (at 60°F) ×
