Materials

A good general source for properties of materials is the Engineering Toolbox, including tables of Density, Specific Heat, and Thermal Conductivity.

Properties of materials may be measured by mass, by volume, by area (for sheets), or by item.

By mass:

• Specific heat capacity is measured in J/kg.K.

By volume:

• Density is measured in kg/m³.
• Volumetric heat capacity is measured in kJ/m³.K.
  Volumetric heat capacity is equal to Specific heat capacity x Density.
• Thermal conductivity (also known as k-value) is measured in W/m.K.

By area:

• Thermal conductance (also known as U-value) is measured in W/m².K.
  Thermal conductance is equal to Thermal Conductivity / Thickness of sheet.
• Area heat capacity (my invention) is measured in kJ/m².K.
  Area heat capacity is equal to Volumetric Heat Capacity x Thickness of sheet.

• Thermal mass is measured in J/K.
  Thermal mass is equal to Volumetric heat capacity x Volume of item.
  Thermal mass is equal to Specific heat capacity x Mass of item.
