What Is This Tool?
This converter transforms heat flux density measurements from the unit horsepower (metric) per square foot to CHU per hour per square foot, aiding in translating surface heat load values between systems used in thermal and HVAC applications.
How to Use This Tool?
-
Enter your heat flux density value in horsepower (metric) per square foot.
-
Select 'horsepower (metric)/square foot' as the input unit and 'CHU/hour/square foot' as the output unit.
-
Click convert to obtain the equivalent CHU/hour/square foot value.
Key Features
-
Converts heat flux density between horsepower (metric)/square foot and CHU/hour/square foot.
-
Supports the interpretation of surface heat loads expressed in mixed legacy units for industrial and building applications.
-
Browser-based and easy to use for quick thermal energy rate conversions per unit area.
Examples
-
2 horsepower (metric)/square foot converts to 2 × 1394.2366002975 = 2788.473200595 CHU/hour/square foot.
-
0.5 horsepower (metric)/square foot converts to 0.5 × 1394.2366002975 = 697.11830014875 CHU/hour/square foot.
Common Use Cases
-
Specifying or converting surface heat loads for industrial furnaces, boilers, or radiators using mixed metric horsepower and imperial area units.
-
Performing heat transfer analysis for engine cooling or heat exchanger surfaces involving legacy unit combinations.
-
Conducting HVAC load calculations and assessing heat gain or loss through building elements on a per-square-foot basis.
-
Sizing radiant heating or cooling equipment based on required heat flux values.
Tips & Best Practices
-
Ensure area units remain consistent as square foot for accurate conversions.
-
Use this tool to aid thermal performance evaluations of insulation and building envelopes.
-
Apply conversions to facilitate proper equipment sizing in heating and cooling applications.
Limitations
-
Conversion accuracy depends on clear energy equivalence definitions for CHU and metric horsepower.
-
Variations in environmental factors like temperature and pressure are not considered in the unit conversion.
-
Mixing different area units may lead to incorrect conversion results.
Frequently Asked Questions
-
What does horsepower (metric)/square foot measure?
-
It measures heat flux density as the rate of heat transfer per unit area using metric horsepower distributed over one square foot.
-
Where is the CHU/hour/square foot unit applied?
-
It is commonly used for HVAC load calculations and specifying thermal energy transfer rates per square foot of surface.
-
Can this tool be used for converting other area units?
-
No, this conversion specifically requires the area to be in square foot to maintain accuracy.
Key Terminology
-
Horsepower (metric)/square foot
-
A heat flux density unit representing one metric horsepower distributed over one square foot area, indicating heat transfer rate per unit area.
-
CHU/hour/square foot
-
A unit describing thermal energy flow rate per square foot, expressed as CHUs delivered or removed per hour.
-
Heat Flux Density
-
The measurement of heat transfer rate per unit surface area, typically expressed in units like W/m² or equivalents.
