Scope

1.1 Heat flux Φ. The amount of heat passing through a surface per unit time, measured in W.
1.2 Heat flux density q. The amount of heat passing through a unit area of a surface per unit
time, measured in W/m².
1.3 Thermal conductivity λ. The heat flux per unit area per unit temperature gradient
perpendicular to the unit area under steady-state conditions, measured in W/(m·K).
