I'm involved in a project and part of it involves heat coefficient and heat conductance. What's the relationship between the two, given that the SI unit for heat coefficient is \$W/mK\$ and the SI unit for heat conductance is \$W/m^2K\$?

\$W\$ - Heat Energy (Watts/Joules per second)
\$m\$ - Length
\$m^2\$ - Area
\$K\$ - Difference in Temperature (Kelvin)

Does anyone know the above parameters for steel? Especially heat conductance.

Thank you.

  • \$\begingroup\$ Googling doesn't really explain much on the conductance. Mostly heat co-efficient. \$\endgroup\$

    \$\begingroup\$ Actually, you've got it backwards: heat transfer coefficient is \$W/m^2K\$ and thermal conductivity is \$W/mK\$. \$\endgroup\$

There is no intrinsic relationship between the two. Heat transfer coefficient ( \$W/m^2K\$) is a measure of how readily heat moves across the interface between two different materials, while thermal conductivity (\$W/mK\$) is a measure of how easily it moves within a single material.
