What does watt/square meter/°C measure in heat transfer?

It measures the rate of heat transfer per unit area per degree Celsius of temperature difference, used to quantify convective or overall thermal conductance.

Why convert heat transfer coefficients to Btu (IT)/hour/square foot/°F?

Conversion enables compatibility with imperial unit systems commonly used in certain regions for energy codes, HVAC sizing, and thermal performance evaluations.

Is the conversion accurate for all temperature conditions?

The conversion assumes consistent temperature difference units and does not consider variations beyond °C to °F equivalence, so actual environmental effects should be considered separately.
