Frequently Asked Questions

What does watt per square meter per degree Celsius measure?
It measures the heat transfer coefficient, indicating the rate of heat transfer per unit area for each degree Celsius of temperature difference.

Why convert from watt/square meter/°C to kilocalorie (IT)/hour/square foot/°C?
Converting allows expression of heat transfer coefficients in units commonly used in HVAC, building energy calculations, and contexts requiring imperial area and energy units.

Can I use this conversion for transient heat transfer situations?
No, this conversion assumes steady-state conditions; transient or complex heat transfer scenarios require more advanced analysis.

Are the temperature difference units °C and K interchangeable for this conversion?
Yes, per the tool's definitions, the per-degree Celsius unit is equivalent to per-Kelvin for temperature differences in this context.

Key Terminology

Heat Transfer Coefficient
A measure of heat transfer rate per unit area for each degree of temperature difference across a surface.
Watt per Square Meter per Degree Celsius (W·m⁻²·°C⁻¹)
A unit quantifying heat transfer coefficient as the power transferred per square meter area per 1 °C temperature difference.
Kilocalorie (IT) per Hour per Square Foot per Degree Celsius
A heat transfer coefficient unit expressing how many international-table kilocalories pass through one square foot of surface per hour for each 1 °C temperature difference.
