What Is This Tool?
This converter helps translate torque or moment of force measurements from pound-force foot (lbf*ft), a U.S. customary unit, to poundal foot (pdl*ft), an imperial/English engineering unit. It supports accurate unit conversions critical for various mechanical and engineering applications.
How to Use This Tool?
-
Enter the torque value in pound-force foot (lbf*ft)
-
Select poundal foot (pdl*ft) as the target unit
-
Click the convert button to get the equivalent torque in poundal foot
-
Review and apply the converted value in your calculations or documentation
Key Features
-
Converts torque from pound-force foot to poundal foot effortlessly
-
Based on exact conversion rate between the two moment of force units
-
Supports engineering and legacy data translation between unit systems
-
Browser-based for quick, on-the-go calculations
-
Useful for automotive, mechanical, and historical equipment contexts
Examples

2 lbf*ft converts to 64.3482099 pdl*ft
-
0.5 lbf*ft converts to 16.087052475 pdl*ft
Common Use Cases
-
Specifying torque for bolts and fasteners in automotive maintenance
-
Rating torque output for small engines and power tools
-
Designing and analyzing mechanical linkages using U.S. customary units
-
Interpreting legacy engineering notes based on poundal-foot units
-
Converting historical torque specifications for restoration or redesign
Tips & Best Practices
-
Always verify the units before applying converted torque values
-
Use conversion results for comparison and documentation rather than precision-critical decisions
-
Understand the context where each torque unit is commonly applied to avoid misuse
-
Be cautious with conversions in high-precision engineering tasks due to minor differences in unit definitions
Limitations
-
Minor precision errors can arise from differences in unit systems and force definitions
-
Poundal foot units are less common today compared to SI or pound-force units
-
Conversions should be used thoughtfully in highly sensitive or safety-critical applications
Frequently Asked Questions
-
What does one pound-force foot represent?
-
It is the torque caused by one pound-force applied perpendicularly at a distance of one foot from a pivot, used commonly in U.S. customary engineering.
-
When should I use poundal foot instead of pound-force foot?
-
Poundal foot is typically used in imperial or English engineering contexts, especially for interpreting legacy data or calculations based on the poundal-foot-second system.
-
Is there any loss of accuracy converting between these units?
-
Because the units originate from different force definitions, small precision discrepancies may occur, so it's best to avoid using this conversion for extremely precise measurements.
Key Terminology
-
Pound-force foot [lbf*ft]
-
A unit of torque representing one pound-force applied at a lever arm one foot long; used widely in U.S. customary engineering.
-
Poundal foot [pdl*ft]
-
A moment of force unit equal to one poundal applied at a one-foot lever arm, common in imperial/English engineering contexts.
-
Moment of force (Torque)
-
The rotational effect produced by a force applied at a distance from a pivot point.
