What Is This Tool?
This converter translates power measurements from foot pound-force per hour, a legacy imperial unit, into kilocalorie (th)/second, a unit commonly used for thermal power or heat transfer rates.
How to Use This Tool?
-
Enter the power value measured in foot pound-force per hour.
-
Select kilocalorie (th)/second as the target unit.
-
Click the convert button to see the equivalent thermal power value.
Key Features
-
Converts between foot pound-force/hour and kilocalorie (th)/second units of power.
-
Based on exact conversion factors linking mechanical and thermal power measures.
-
Enables interpretation of legacy imperial power data in terms of heat flow rates.
Examples
-
100 foot pound-force/hour converts to approximately 9.0013 × 10⁻⁶ kilocalorie (th)/second.
-
10,000 foot pound-force/hour equals about 9.0013 × 10⁻⁴ kilocalorie (th)/second.
Common Use Cases
-
Converting small mechanical power ratings from legacy equipment into thermal units for engineering analysis.
-
Documenting energy throughput in older reports using foot and pound-force units.
-
Comparing imperial power specs with SI units when updating designs or thermal system data.
Tips & Best Practices
-
Ensure you understand the context of the original unit to apply meaningful conversions.
-
Use the converter for specialized or historical data where small power levels are relevant.
-
Verify unit selections carefully to avoid misinterpretation between mechanical and thermal power.
Limitations
-
Foot pound-force/hour is a very small and uncommon unit in modern applications.
-
Conversions result in extremely small values, limiting use mainly to niche or legacy contexts.
-
Precision depends on constants and the non-SI basis of the foot pound-force unit.
Frequently Asked Questions
-
What does foot pound-force per hour measure?
-
It is a unit of power representing the amount of mechanical work equal to one foot-pound-force performed each hour.
-
When should I convert foot pound-force/hour to kilocalorie (th)/second?
-
When you need to interpret small mechanical power rates in thermal power terms, especially for legacy equipment or thermal system design.
-
Is foot pound-force/hour commonly used today?
-
No, it is mostly used in legacy or historical engineering documents and not common in modern systems.
Key Terminology
-
Foot pound-force/hour
-
A non-SI power unit representing one foot-pound-force of work performed every hour.
-
Kilocalorie (th)/second
-
A unit of thermal power measuring the rate of heat transfer equal to one thermochemical kilocalorie per second.
-
Power
-
The rate at which work is performed or energy is transferred.
