What Is This Tool?
This converter lets you transform power values from pound-foot per hour, an imperial unit representing mechanical work over time, into exajoule per second, a unit for extremely large power flows used in astrophysics and climate science.
How to Use This Tool?
-
Enter the power value in pound-foot per hour.
-
Select pound-foot/hour as the input unit.
-
Choose exajoule/second as the output unit.
-
Click the convert button to obtain the equivalent power in EJ/s.
-
Review the result and use it for scientific or historical comparisons.
Key Features
-
Converts mechanical power from pound-foot/hour to exajoule/second accurately.
-
Handles conversion between extremely low and extremely high power units.
-
Useful for comparing legacy mechanical power with planetary-scale energy rates.
-
Includes examples to illustrate the conversion process.
-
Browser-based and easy to use with no installation required.
Examples
-
Converting 10 lbf*ft/h results in 3.7661609675818e-21 EJ/s.
-
Converting 100 lbf*ft/h results in 3.7661609675818e-20 EJ/s.
Common Use Cases
-
Expressing very low continuous mechanical power in legacy imperial units.
-
Documenting specifications of vintage machinery using foot-pound units.
-
Estimating hand-crank or slow winch work rates from older ratings.
-
Comparing historic mechanical outputs with planetary or stellar energy rates.
-
Conducting systemic energy studies relating human power use to planetary scales.
Tips & Best Practices
-
Ensure input values reflect continuous mechanical power in pound-foot/hour.
-
Use the conversion mainly for scientific scale comparisons due to vast differences in magnitude.
-
Confirm unit selection before converting to avoid errors.
-
Refer to examples for understanding the expected output format.
-
Be aware that typical mechanical powers convert to extremely small values in EJ/s.
Limitations
-
Pound-foot/hour represents very low power levels while exajoule/second measures extraordinarily large power.
-
Direct practical conversion is uncommon except for scale comparison in scientific studies.
-
The extreme difference in magnitudes results in minuscule output values for typical inputs.
Frequently Asked Questions
-
What does pound-foot/hour measure?
-
It measures mechanical power as the rate of work done, in imperial units, defined as one foot-pound force per hour.
-
What is an exajoule per second?
-
An exajoule per second is a unit of power equal to 10^18 joules every second, commonly used to express vast energy rates like stellar luminosities.
-
Why convert between these vastly different units?
-
Converting allows comparison between very small mechanical power levels and enormous planetary or astrophysical energy flows for scientific analysis.
Key Terminology
-
Pound-foot/hour (lbf·ft/h)
-
An imperial unit of power describing work performed at a rate of one foot-pound force per hour.
-
Exajoule/second (EJ/s)
-
A large power unit representing energy flow at 10^18 joules per second, equal to one exawatt.
-
Mechanical power
-
The rate at which mechanical work is done, expressed in various units depending on the measurement system.
