The rate of heat flow between two systems is measured in watts (joules per second). The formula for rate of heat flow is , where is the rate of heat flow; is the thermal conductivity factor; A is the surface area; is the change in temperature and is the thickness of the material. is called the temperature gradient and is always negative because of the heat of flow always goes from more thermal energy to less).
