VCF Calculator

Volume Correction Factor (VCF)

CTL, commonly referred to as VCF, is a standardized computed factor used to correct for the thermal expansion of liquids, primarily, liquid hydrocarbons. The CTL/VCF is typically a number between 0 and 2, rounded to 5 decimal places, which when multiplied by the observed volume of a liquid, will return the corrected value to a standardized base temperature and density. As such, the CTL/VCF value is computed using the observed temperature and density of a liquid.

Using the calculator below, enter the Temperature in degrees Fahrenheit (°F), and the Density in Degrees API. These two numbers will be computed with the coefficient of thermal expansion at 60°F (α₆₀) based on the selected commodity and return the CTL/VCF Value.
