What Is This Tool?
This converter allows you to translate power values from the imperial unit foot pound-force per hour (ft·lbf/hr) to the SI-derived centijoule per second (cJ/s). It supports users working with legacy mechanical power data and small-scale modern power measurements in scientific and engineering contexts.
How to Use This Tool?
-
Enter the power value in foot pound-force per hour (ft·lbf/hr)
-
Select the output unit as centijoule per second [cJ/s]
-
Click convert to view the equivalent power value in cJ/s
-
Use the result to compare or update designs and analyze low power systems
Key Features
-
Converts legacy foot pound-force/hour values to precise centijoule/second units
-
Supports understanding of very low power levels in both imperial and metric systems
-
Browser-based and easy to use with clear input and output
-
Ideal for engineering documentation and scientific measurement tasks
Examples
-
Convert 10 foot pound-force/hour to get 0.376616097 centijoule/second [cJ/s]
-
Convert 50 foot pound-force/hour to get 1.883080485 centijoule/second [cJ/s]
Common Use Cases
-
Expressing very small mechanical power in legacy imperial-system engineering documents
-
Describing mechanical work performed per hour in historical or field reports using foot and pound-force units
-
Converting older imperial power specifications to SI units for comparison or updating designs
-
Reporting power draw of low-power sensors, IoT nodes, or wearable devices
-
Characterizing small steady outputs in laboratory tests involving photodiodes or LEDs
-
Assessing energy harvested by micro-energy harvesters in prototype systems
Tips & Best Practices
-
Ensure unit scales and time bases are correctly applied when converting between these units
-
Use centijoule/second for more precise power representation in seconds rather than hourly rates
-
Refer to engineering documentation for context on when to employ these conversions
-
Double-check conversions when updating legacy reports to SI units for accuracy
Limitations
-
Foot pound-force/hour is a non-SI unit that measures low power over an hour, with less precision
-
Centijoule/second is SI-compatible and measures power per second, so conversion must account for time scale differences
-
Care is needed to avoid errors when analyzing instantaneous versus steady-state power levels
Frequently Asked Questions
-
What is a foot pound-force/hour?
-
It is a non-SI power unit representing one foot-pound-force of work performed or energy transferred every hour, often used for very small mechanical power in imperial units.
-
What does centijoule per second represent?
-
A centijoule per second is a unit of power equal to one hundredth of a joule transferred each second, useful for expressing very small steady power levels in scientific and engineering fields.
-
Why convert foot pound-force/hour to centijoule/second?
-
Converting allows translating older imperial power measurements into precise SI-derived units suitable for modern scientific analysis, aiding in design updates and comparison of low power systems.
