\(\large{ d }\) = penetration depth | \(\large{in}\) | \(\large{mm}\) |
\(\large{ k }\) = thermal conductivity | \(\large{\frac{Btu-ft}{hr-ft^2-F}}\) | \(\large{\frac{W}{m-K}}\) |
\(\large{ \alpha }\) (Greek symbol alpha) = thermal diffusivity | \(\large{\frac{ft^2}{sec}}\) | \(\large{\frac{m^2}{s}}\) |
\(\large{ t }\) = time | \(\large{sec}\) | \(\large{s}\) |
