Frequently Asked Questions
-
What does kilocalorie (IT)/hour/square meter/°C measure?
-
It measures the steady heat flow per unit area per degree Celsius temperature difference, quantifying kilocalories passing per hour through one square meter of material.
-
In which fields is Btu (IT)/second/square foot/°F commonly used?
-
It is commonly used in US customary engineering for convective heat transfer coefficients, refrigeration, HVAC, and heat exchanger performance ratings.
-
Why is precise handling of the conversion factor important?
-
Because the conversion factor has a small magnitude, precise calculation helps avoid rounding errors that can impact thermal performance evaluations.
