What is the Heat Transfer Calculator & How does it work?
Heat transfer is the process of energy being transferred from one object to another due to a temperature difference. There are three primary modes of heat transfer: conduction, convection, and radiation.
Q = kAfrac{Delta T}{L}
Q = Heat Transfer Rate (W), k = Thermal Conductivity (W/mK), A = Area (mΒ²), Delta T = Temperature Difference (K), L = Thickness (m)
Conduction occurs through direct contact between particles. Convection involves the movement of fluids or gases, and radiation is the transfer of energy through electromagnetic waves.

Frequently Asked Questions
What is the formula for heat transfer by conduction?
The formula for heat transfer by conduction is Q = kAΞ”T/L, where Q is the heat transfer rate (W), k is the thermal conductivity (W/mK), A is the area (mΒ²), Ξ”T is the temperature difference (K), and L is the thickness (m).
How does convection differ from conduction?
Convection involves the movement of fluids or gases, transferring heat through circulation, while conduction occurs through direct contact between particles without any bulk motion.
What is radiation in the context of heat transfer?
Radiation is the transfer of heat energy through electromagnetic waves, which can occur even in a vacuum and does not require any medium for transmission.
How do I calculate the thermal conductivity of a material?
Thermal conductivity (k) is typically provided as a property of the material. You can find it in engineering handbooks or material data sheets specific to the substance you are working with.
Can this calculator be used for all types of heat transfer?
This calculator specifically addresses conduction and requires inputs like thermal conductivity, area, temperature difference, and thickness. For other modes like convection or radiation, different formulas and parameters would be needed.
What units should I use for the inputs in this calculator?
Use Watts (W) for heat transfer rate, Watts per meter Kelvin (W/mK) for thermal conductivity, square meters (mΒ²) for area, Kelvin (K) for temperature difference, and meters (m) for thickness.
How does the thickness of a material affect heat transfer?
Thicker materials generally have higher resistance to heat transfer. As thickness increases, the heat transfer rate decreases, assuming all other factors remain constant.
