What Is This Tool?
This tool converts heat transfer coefficient measurements from joule per second per square meter per Kelvin (J·s⁻¹·m⁻²·K⁻¹) to Btu (thermal) per second per square foot per degree Fahrenheit (Btu/th·s⁻¹·ft⁻²·°F⁻¹). It enables users to switch between SI and imperial units used in thermal energy transfer evaluations.
How to Use This Tool?
- Enter the value in joule/second/square meter/K you wish to convert.
- Select the target unit Btu (th)/second/square foot/°F.
- Click convert to obtain the corresponding value in imperial units.
- Use the results for building envelope analysis, HVAC sizing, or heat exchanger design.
Key Features
- Supports conversion of heat transfer coefficients between SI and imperial units.
- Quickly translates values for building and HVAC industry standards.
- Browser-based and easy-to-use interface requiring no installation.
- Includes real-world examples to demonstrate the conversion process.
- Ensures compatibility with engineering calculations and thermal assessments.
Examples
- 10 joule/second/square meter/K equals 0.000489522 Btu (th)/second/square foot/°F.
- 100 joule/second/square meter/K equals 0.00489522 Btu (th)/second/square foot/°F.
Common Use Cases
- Calculating U-values and heat loss in building components like walls and windows.
- Defining convective heat transfer coefficients in HVAC and aerodynamic cooling contexts.
- Designing, rating, and evaluating heat exchangers and insulation performance using either SI or imperial units.
