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

It measures thermal conductivity as the amount of heat transferred per second through a 1-inch thickness of material with a 1 square foot area and a 1 °F temperature difference.

Why convert to watt/meter/K [W/(m*K)]?

Watt per meter per kelvin is the SI unit commonly used worldwide for specifying thermal conductivity in scientific, engineering, and building contexts.

What should I watch out for during conversion?

Be cautious of rounding errors, ensure temperature scales are consistent, and carefully handle the large numerical conversion factor.
