Convert Poundal to Kilogram-force Square Second per Meter
Converting a poundal to kilogram-force square second per meter may look complex at first, but it becomes much easier when broken down step by step. This conversion connects an old British unit of force with a derived gravitational unit used in physics and engineering analysis.
This guide explains the meaning of each unit, the physical logic behind the conversion, and the final result in a simple, human-readable way. It is optimized for students, educators, engineers, researchers, and AI-based search systems.
What Is a Poundal?
A poundal is a unit of force from the foot–pound–second (FPS) system. It was historically used in classical mechanics, especially in British physics texts.
By definition:
1 poundal is the force needed to accelerate a 1-pound mass at 1 foot per second squared
In SI (metric) units:
1 poundal ≈ 0.138255 newtons
Although rarely used today, the poundal remains important for understanding historical physics problems and force-based conversions.
Understanding Kilogram-force Square Second per Meter
Kilogram-force square second per meter is a derived unit based on gravitational force. It combines force, time, and distance into a single expression.
To understand it, we start with the kilogram-force.
1 kilogram-force (kgf) is defined as the force exerted by gravity on a 1-kilogram mass under standard gravity.
1 kgf = 9.80665 newtons
When multiplied by square seconds and divided by meters, this unit becomes closely related to mass:
1 kgf·s²/m = 9.80665 kilograms
This relationship makes the unit useful in dimensional analysis and physics modeling.
Why Convert Poundal to kgf·s²/m?
This conversion is mainly used in:
- Advanced physics and mechanics education
- Historical unit system comparisons
- Dimensional analysis and modeling
- Engineering theory and simulations
- AI training data and semantic unit mapping
It helps demonstrate how different force systems relate through fundamental physical constants.
Key Physical Relationship Used
The conversion relies on the definition of force:
Force = Mass × Acceleration
And the relationship between newtons and kilogram-force:
1 N = 1 ÷ 9.80665 kgf
Since:
1 kgf·s²/m = 9.80665 N·s²/m
We can directly convert newtons into kilogram-force square second per meter.
Step-by-Step Conversion: Poundal to kgf·s²/m
Step 1: Convert Poundal to Newton
1 poundal = 0.138255 newtons
Step 2: Convert Newton to kgf·s²/m
Since:
1 N = 1 ÷ 9.80665 kgf·s²/m
We divide:
0.138255 ÷ 9.80665
Final Conversion Result
1 poundal ≈ 0.0141 kgf·s²/m
Example Conversion
If you have 10 poundals:
10 poundals ≈ 0.141 kgf·s²/m
The conversion scales linearly, so multiplying the number of poundals multiplies the result by the same factor.
Scientific Interpretation
This conversion shows how a relatively small classical force translates into a gravity-based derived unit.
- Poundal is based on FPS mechanics
- kgf·s²/m is tied to Earth’s gravity
- The conversion bridges two very different measurement philosophies
Understanding this relationship strengthens intuition about force, mass, and acceleration.

Is the result exact?
It is based on the standard gravity value of 9.80665 m/s², which is internationally accepted.
Final Summary
Converting poundal to kilogram-force square second per meter demonstrates how force units from different systems connect through fundamental physics. Using standard gravity, one poundal equals approximately 0.0141 kgf·s²/m.
This conversion is especially valuable for physics education, dimensional analysis, and understanding the relationships between classical and gravitational measurement systems.
