Thermal expansion coefficients for various materials. For isotropic materials the coefficients linear thermal expansion α and volumetric thermal expansion αV are related by αV = 3 α . For liquids usually the coefficient of volumetric expansion is listed and linear expansion is calculated here for comparison.
The linear coefficient of thermal expansion ( a) describes the relative change in length of a material per degree temperature change. As shown in the following equation, a is the ratio of change in length ( D l) to the total starting length (l i) and change in temperature ( D T).

The coefficient of thermal expansion is defined as the change in length or volume of a material for a unit change in temperature. The overall coefficient is the linear thermal expansion (in.) per degree Fahrenheit or Celsius.
A coefficient of thermal expansion… is the ratio of the fractional change in size of a material to its change in temperature. is represented by the symbol α (alpha) for solids and β (beta) for liquids. uses the SI unit inverse kelvin (K−1 or 1/K) or the equivalent acceptable non SI unit inverse degree Celsius (℃−1 or 1/℃).

Linear Expansion. To a first approximation, the change in length measurements of an object ( linear dimension as opposed to, for example, volumetric dimension) due to thermal expansion is related to temperature change by a linear expansion coefficient. It is the fractional change in length per degree of temperature change.

THE COEFFICIENT OF LINEAR thermal expansion (CTE, a, or a 1) is a material property that is indicative of the extent to which a material expands upon heating.Different substances expand by different amounts. Over small temperature ranges, the thermal expansion of uniform linear objects is proportional to temperature change.
The volumetric thermal expansion coefficient can be measured for all substances of condensed matter (liquids and solid state). The linear thermal expansion can only be measured in the solid state and is common in engineering applications.
