Where:

  • q is the rate of heat transfer (in watts or joules per second)
  • k is the thermal conductivity of the material (in watts per meter per kelvin)
  • A is the cross-sectional area through which heat is transferred (in square meters)
  • ΔT is the temperature difference across the material (in kelvin or degrees Celsius)
  • L is the thickness of the material through which heat is transferred (in meters)
