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

It measures thermal conductivity as the heat transfer rate through a material one foot thick and one square foot in area per hour for a one degree Fahrenheit temperature difference.

Why convert to Btu (IT) inch/second/sq. foot/°F?

This conversion provides thermal conductivity in US customary units with a focus on per second time intervals and per inch thickness, useful for precise heat transfer analyses.

Is this tool suitable for converting to SI units like W/(m·K)?

No, this tool converts between two Imperial units. To convert to SI units, use a specialized converter designed for metric conversions.
