Thermal Expansion Calculator Linear or Volumetric
Linear thermal expansion is the most common calculation used to estimate the expansion caused by a change in temperature. The Coefficient of Linear Thermal Expansion is commonly displayed as a product of a length/length temperature unit. as this is the case the unit of length does not matter provided both units of length are the same.

Thermal expansion. When materials are heated their size and volume increase in small increments in a phenomenon known as thermal expansion. Expansion values vary depending on the material being heated. The coefficient ratio of thermal expansion indicates how much a material expands per 1℃ (2.2℉) rise in temperature.

Thermal Expansion and Contraction
An average value for the coefficient of thermal expansion of concrete is about 10 millionths per degree Celsius (10x10-6 /C) although values ranging from 7 to 12 millionths per degree Celsius have been observed. This amounts to a length change of 1.7 centimeters for every 30.5 meters of concrete subjected to a rise or fall of 38 degrees Celsius.
