Why does the area unit remain in square foot during conversion?

The conversion changes the energy and temperature units while preserving the area unit, which remains imperial to maintain consistency in certain HVAC and building energy calculations.

Can this tool be used for fully metric unit conversions?

No, this tool retains the square foot area unit, so it is not designed for fully metric unit systems involving square meters.

What should I be cautious about when converting between °F and °C units?

Because temperature difference units vary between degrees Fahrenheit and Celsius, it is important to consider their different scales when interpreting converted heat transfer coefficients.
