What does watt per square meter per kelvin measure?

It represents the heat flux transferred per unit area for a one-kelvin temperature difference between a surface and its surroundings.

Why convert to CHU/hour/square foot/%b0C?

To translate SI heat transfer coefficients into units used in regions applying imperial measurements for building and HVAC thermal analysis.

Are temperature differences handled correctly between units?

Yes, differences in Kelvin and degree Celsius scales are accounted for since their increments are equivalent in magnitude.
