A clear answer. Here’s how.

Uses watts per metre kelvin. Temperature units represent intervals without an offset. BTU is International Table; calories are thermochemical. Conductivity is a material property and is distinct from total thermal conductance or a complete wall’s U-value. Values are rounded to 12 significant figures for display.
