What does 1 Btu (th) inch/second/sq. foot/°F represent?

It represents the thermal conductivity transferring one thermochemical British thermal unit per second through a 1-inch thick material with a 1 square foot area per 1 °F temperature difference.

Why convert thermal conductivity units from Imperial to calorie units?

Converting helps to use legacy data reported in older CGS-based engineering handbooks and laboratory results with modern analyses.

Can this tool be used for transient heat transfer calculations?

No, the unit conversion assumes steady-state conduction and does not cover transient or anisotropic effects.
