Overview
Thermal conductivity is the property of a material to conduct heat. This calculator uses Fourier's Law of Heat Conduction to determine the rate of heat transfer.
💡
Pro Tips
Metals like copper and silver have very high thermal conductivity.
Gases and insulation materials have very low thermal conductivity.
The rate of heat transfer (P) is measured in Watts (Joules per second).

Fun Facts
"Diamond has the highest thermal conductivity of any natural substance, even better than silver."
"Air is a very poor thermal conductor, which is why double-pane windows work so well."
"Thermal conductivity in gases increases with temperature, while in most solids, it decreases."
