What does kilocalorie (IT)/hour/square meter measure?

It measures heat flux density, representing the rate of heat transfer per hour through one square meter using International Table kilocalories.

Why convert to Btu (th)/hour/square foot?

Because Btu (th)/hour/square foot is a common unit used in North American building science and HVAC for expressing heat flux density.

Are there limitations to this conversion?

Yes, the conversion assumes consistent unit definitions and steady conditions; it does not account for transient heat fluxes or specific material resistances.
