Linear Volume Expansion Via Thermal Expansion

Notation and Units

Metric and Imperial Units

The above formulas may be used with both imperial and metric units. As with all calculations care must be taken to keep consistent units throughout with examples of units which should be adopted listed below:


  • V = volume, in4 or mm4
  • VF = final volume, in4 or mm4
  • T = change in temperature, ᵒK or ᵒC
  • V = change in volume, in4 or mm4
  • α = coefficient of thermal expansion, ᵒK-1 or ᵒC-1
