Converting thermal conductivity units is essential for engineers, scientists, and professionals working in heat transfer applications. One common conversion is from Btu (IT) inch/hour/sq. foot/°F to kW/m/K.
In this guide, we’ll explain the conversion formula, provide step-by-step examples, and discuss practical applications.
Understanding the Units
- Btu (IT) inch/hour/sq. foot/°F: A unit of thermal conductivity in the Imperial system, representing heat flow in British Thermal Units (IT) per inch of thickness per hour per square foot per degree Fahrenheit.
- kW/m/K: A metric (SI) unit of thermal conductivity, representing kilowatts of heat flow per meter of thickness per Kelvin (or degree Celsius).
Conversion Formula
To convert Btu (IT) inch/hour/sq. foot/°F to kW/m/K, use the following formula:1 Btu (IT) inch/hour/sq. foot/°F=0.0001441314 kW/m/K1Btu (IT) inch/hour/sq. foot/°F=0.0001441314kW/m/K
General Formula:kW/m/K=Btu (IT) inch/hour/sq. foot/°F×0.0001441314kW/m/K=Btu (IT) inch/hour/sq. foot/°F×0.0001441314
Step-by-Step Conversion Examples
Example 1: Convert 5 Btu (IT) inch/hour/sq. foot/°F to kW/m/K
5×0.0001441314=0.000720657 kW/m/K5×0.0001441314=0.000720657kW/m/K
Example 2: Convert 10 Btu (IT) inch/hour/sq. foot/°F to kW/m/K
10×0.0001441314=0.001441314 kW/m/K10×0.0001441314=0.001441314kW/m/K
Example 3: Convert 100 Btu (IT) inch/hour/sq. foot/°F to kW/m/K
100×0.0001441314=0.01441314 kW/m/K100×0.0001441314=0.01441314kW/m/K
Practical Applications
- Building Insulation: Comparing thermal conductivity values in different unit systems for insulation materials.
- Engineering Design: Converting units for heat transfer calculations in mechanical and civil engineering.
- Scientific Research: Ensuring consistency in thermal conductivity measurements across studies.
Conclusion
Converting Btu (IT) inch/hour/sq. foot/°F to kW/m/K is straightforward using the multiplier 0.0001441314. This conversion is crucial for professionals working with thermal properties in different unit systems.
