What does Btu (th) inch/hour/sq. foot/°F measure?

It measures thermal conductivity as heat flow in thermochemical British thermal units per hour through a 1 inch thick, 1 square foot area for a 1 °F temperature difference.

Why convert to calorie (th)/second/cm/°C?

Converting allows compatibility with older cgs-based data and laboratory measurements reported in thermochemical calories per second per centimeter per degree Celsius.

Can this tool be used for modern SI units?

While it converts between imperial and cgs legacy units, converting to SI units like watts per meter Kelvin involves additional steps beyond this converter.
