What does horsepower (metric)/square foot measure?

It measures heat flux density by expressing the power in metric horsepower distributed over one square foot of area, indicating the rate of heat transfer per unit area.

Where is Btu (th)/second/square inch commonly used?

This unit is often used in fire testing, fire-protection engineering, welding experiments, and propulsion plume thermal analysis, especially when dealing with very high localized heat fluxes.

It is useful for translating measurements that combine metric power units with imperial area units into a purely imperial measurement used in thermal engineering and fire testing.

How to Use This Tool?

Enter the heat flux density value in horsepower (metric)/square foot.
Select the original unit as horsepower (metric)/square foot.
Choose the target unit as Btu (th)/second/square inch.
Click convert to obtain the result in Btu (th)/second/square inch.

Key Features

Converts heat flux density between metric horsepower per square foot and Btu (th) per second per square inch.
Supports engineering applications involving heat transfer rates over surface areas with mixed unit systems.
Provides straightforward calculations using a set conversion rate.
Perfect for analyzing legacy data or equipment that mix metric and imperial units.

Examples

Converting 10 horsepower (metric)/square foot gives approximately 0.048443391 Btu (th)/second/square inch.
When converting 50 horsepower (metric)/square foot, the result is roughly 0.242216955 Btu (th)/second/square inch.

Common Use Cases

Specifying surface heat loads in industrial furnaces, boilers, or radiators using mixed metric horsepower and imperial area units.
Comparing heat flux values in thermal analysis of engine cooling surfaces or heat exchangers that use legacy unit systems.
Quantifying radiant heat fluxes during fire testing and fire-protection engineering of materials.
Measuring localized high heat loads from welding, plasma torches, or propulsion plume experiments.
Specifying heat inputs on small surface areas in industrial furnace or burner testing with imperial units.

Tips & Best Practices

Always verify that the units used correspond to consistent definitions of metric horsepower and British thermal units for accuracy.
Use this conversion primarily for steady-state heat flux density scenarios.
Cross-check converted values especially when working with legacy datasets containing mixed units.
Be cautious when applying conversions to rapidly changing or transient thermal conditions.

Limitations

Accuracy depends on consistent definitions of the metric horsepower and British thermal unit standards.
Converted heat flux values are approximate due to rounding in underlying unit definitions.
This conversion is generally suited for steady-state conditions and might not fit transient heat flux scenarios.
