Why are joule/second/square meter/K and kilocalorie (IT)/hour/square foot/%b0C used for heat transfer coefficients?

Both units measure the rate of heat flow per unit area per temperature difference, with joule/second/square meter/K common in metric systems and kilocalorie (IT)/hour/square foot/%b0C used primarily in imperial and HVAC contexts.

Can I use this conversion for temperature differences in degrees Celsius and Kelvin?

Yes, since the size of one degree is the same in both Celsius and Kelvin, the conversion assumes equivalent temperature differentials.

Is the conversion rate valid for all calorie definitions?

No, this conversion specifically applies to the international-table kilocalorie and may not be accurate for other calorie types.
