Coefficient of Thermal Expansion CTE 10-6 C-1. V volume of unit m 3 ft 3 m mass of unit kg lb The change in the units volume when temperature changes can be expressed as. A quantitative characterization of thermal expansion at constant pressure is provided by the isobaric thermal expansion coefficient which is often called the coefficient of volume or cubical expansion.
