 *Formula for CCAI:

 CCAI=D-140.7 \log (\log (V+0.85))-80.6-210 \ln \left (\frac{t+273}{323} \right )

 which is equivalent to:

CCAI=D-140.7 \log (\log (V+0.85))-80.6-483.5 \log \left (\frac{t+273}{323} \right )

Where:

D= density at 15°C (kg/m3)
V= viscosity (cST)
t = viscosity temperature (°C)
