Under thermal expansion, therefore, to convert the coefficient of linear expansion from degrees celsius to kelvin, you only have to swap the symbols. Use these free tools to calculate thermal expansion in both linear and volumetric methods, just add your coefficient and some dimensions.

Thermal expansion: thermal expansion, the general increase in the volume of a material as its temperature is increased it is usually expressed as a fractional change in length or volume per unit temperature change a linear expansion coefficient is usually employed in describing the expansion of a solid, while a. Coefficient of thermal expansion: the ratio that a material expands in accordance with changes in temperature is called the coefficient of thermal expansionbecause fine ceramics possess low coefficients of thermal expansion, their distortion values, with respect to changes in temperature, are low.
