What Can This Heat Transfer Calculator Do?
This tool supports different heat transfer calculations:
🔥 Conduction
Heat moves through a solid material like a wall, a metal rod, or a window.
🌬️ Convection
Heat transfer between a surface and a moving fluid, like air or water.
♨️ Heat Energy
Total heat energy gained or lost by a substance.
You can switch between these options depending on what you need to find.

How the Calculation Works (Simple Explanation)
Heat always flows from a hotter place to a cooler place.
For Conduction
Heat moves through a solid material.
The calculator uses this idea:
More area + bigger temperature difference = more heat flow
Thicker material = less heat flow
For Convection
Heat moves between a surface and moving air or liquid. Faster movement usually means more heat transfer.
For Heat Energy
Heat energy depends on how much a material’s temperature changes and how much material there is.
Easy Example (Conduction)
Imagine a wall with:
- Thermal conductivity = 0.7 W/m·K
- Area = 12 m²
- Temperature difference = 15°C
- Thickness = 0.25 m
Enter these values above. The calculator quickly tells you how much heat is passing through the wall.

Frequently Asked Questions
What is the difference between conduction and convection?
Conduction is heat moving through a solid. Convection is heat moving with air or liquid.
What is thermal conductivity (k)?
It shows how easily heat passes through a material. Metal has high conductivity. Wood has low conductivity.
Can I use °C or K for temperature difference?
Yes. A temperature difference in °C is the same as in Kelvin.
Why do I need the area?
A larger area allows more heat to flow through.
Is this calculator good for home insulation planning?
Yes. It helps estimate how much heat is lost or gained through walls, floors, and roofs.
