Frequently Asked Questions
-
What units does this converter translate between?
-
It converts heat transfer coefficients from watt per square meter per degree Celsius to Btu (thermal) per second per square foot per degree Fahrenheit.
-
What is watt/square meter/°C used for?
-
It represents the rate of heat transfer per unit area per unit temperature difference, commonly used in engineering to calculate heat loss and convective heat transfer.
-
Why is this conversion important for HVAC design?
-
Because HVAC equipment and heat load calculations are often specified in imperial units, converting metric heat transfer coefficients is essential for accurate design and analysis.
