What does Btu (IT)/hour/square foot/°F measure?

It measures the rate of heat flow per hour through one square foot of area for each degree Fahrenheit of temperature difference, representing the overall heat transfer coefficient in imperial units.

Why convert to kilocalorie (IT)/hour/square meter/°C?

Converting to this metric unit helps align heat transfer coefficient metrics with regional standards, supporting international collaboration and consistent energy modeling.

Can this tool be used for dynamic heat transfer calculations?

No, this conversion assumes steady-state heat transfer conditions; dynamic or transient scenarios require specialized methods.
