Thermal Conductivity Conversion - Convert W/(m⋅K), BTU/(hr⋅ft⋅°F), and More
Understanding Thermal Conductivity Measurements
Thermal conductivity measurement is crucial in materials science, engineering, and energy efficiency. The watt per meter-kelvin (W/(m·K)) is the base unit in the International System of Units (SI), while BTU/(hr·ft·°F) and other units are used in different regions and industries. Understanding thermal conductivity conversions is essential for insulation, electronics cooling, and heat exchanger design.
Common Thermal Conductivity Units
SI Units
- Watt per meter-kelvin (W/(m·K)) - Base unit
- Kilowatt per meter-kelvin (kW/(m·K)) - 1000 W/(m·K)
- Milliwatt per meter-kelvin (mW/(m·K)) - 0.001 W/(m·K)
Other Units
- BTU/(hr·ft·°F) - Common in US industry
- Calorie/(s·cm·°C) - CGS system
- BTU·in/(hr·ft²·°F) - Building insulation
- Watt per centimeter-°C (W/(cm·°C)) - Laboratory use
Common Applications
| Field | Common Units | Typical Uses |
|---|---|---|
| Building Insulation | W/(m·K), BTU/(hr·ft·°F) | Wall, roof, window insulation |
| Electronics Cooling | W/(m·K) | Heat sink, thermal interface materials |
| Materials Science | W/(m·K), cal/(s·cm·°C) | Material selection, research |
| HVAC | BTU/(hr·ft·°F) | Heating, ventilation, air conditioning |
Conversion Tips
- 1 W/(m·K) ≈ 0.5778 BTU/(hr·ft·°F)
- 1 BTU/(hr·ft·°F) ≈ 1.7307 W/(m·K)
- 1 cal/(s·cm·°C) ≈ 418.68 W/(m·K)
- Higher thermal conductivity means better heat transfer
