# Heat Transfer Coefficient Converter

Heat transfer is a crucial aspect in various engineering and scientific applications, ranging from designing energy-efficient buildings to optimizing industrial processes. One key parameter that plays a significant role in heat transfer is the Heat Transfer Coefficient.

The Heat Transfer Coefficient is a measure of how effectively heat is transferred through a material or between different materials. It is defined as the amount of heat transferred per unit area per unit temperature difference.

It is denoted by various units, and understanding these units is essential for accurate calculations and meaningful comparisons. Here, we'll explore some common units and provide a converter tool to facilitate seamless conversions.

• Watt / meter² / K (W/m²/K): The amount of heat in watts transferred through one square meter of material for a temperature difference of one Kelvin.
Conversion Factor: 1 W/m²/K = 1 W/m²/K (Base Unit)

• Watt / meter² / °C (W/m²/°C): Similar to W/m²/K, but for a temperature difference of one degree Celsius. Because a temperature difference of one Kelvin is equal to a temperature difference of one Celsius, both units are equal.
Conversion Factor: 1 W/m²/°C = 1 W/m²/K

• Kilocalorie (IT) / hour / meter² / °C (kcal/h/m²/°C): The amount of heat in kilocalories transferred through one square meter of material for a temperature difference of one degree Celsius over an hour.
Conversion Factor: 1 kcal/h/m²/°C = 1.163 W/m²/K

• Kilocalorie (IT) / hour / foot² / °C (kcal/h/ft²/°C): Similar to kcal/h/m²/°C, but for square feet in the imperial system.
*Conversion Factor: 1 kcal/h/ft²/°C ≈ 12.5184 W/m²/K**

• Btu / second / foot² / °F (Btu/s/ft²/°F): The amount of heat in British Thermal Units transferred through one square foot for a temperature difference of one degree Fahrenheit over a second.
Conversion Factor: 1 Btu(IT)/s/ft²/°F ≈ 20,441.748 W/m²/K; 1 Btu(th)/s/ft²/°F ≈ 20,428.0772 W/m²/K

• Btu / hour / foot² / °F (Btu/h/ft²/°F): The amount of heat in British Thermal Units transferred through one square foot for a temperature difference of one degree Fahrenheit over an hour.
Conversion Factor: 1 Btu(IT)/h/ft²/°F ≈ 5.6783 W/m²/°C; 1 Btu(th)/h/ft²/°F ≈ 5.6744 W/m²/°C

• CHU / hour / foot² / °C (CHU/h/ft²): The amount of heat in Centigrade Heat Units transferred through one square foot for a temperature difference of one degree Celsius over an hour.
Conversion Factor: 1 CHU/h/ft² ≈ 5.6783 W/m²/°C
