Why is it important to convert heat transfer coefficients between these units?

Because building and HVAC designs use both metric and imperial units globally, converting between kilocalorie (IT)/hour/m²/°C and CHU/hour/ft²/°C ensures consistent thermal performance comparisons and compliance with regional standards.

Can I use this conversion for non-steady-state heat flow?

No, this conversion specifically applies to steady-state heat flow conditions and assumes consistent measurement protocols.

What should I watch out for when converting these units?

Pay attention to differences in temperature scale usage and area units, as well as rounding and measurement precision, to avoid mistakes in calculations.
