What Is This Tool?
This converter helps translate forces measured in pound foot per square second, a legacy FPS unit, into attonewtons, an extremely small SI force unit. It is useful for bridging classical mechanics values and ultra-sensitive force scales in scientific contexts.
How to Use This Tool?
-
Input the force value in pound foot/square second.
-
Select pound foot/square second as the from-unit.
-
Choose attonewton [aN] as the target unit.
-
Click the convert button to get the equivalent force in attonewtons.
Key Features
-
Converts pound foot/square second (poundal) to attonewton [aN].
-
Supports conversion from imperial FPS force units to ultra-small SI units.
-
Browser-based and user-friendly interface for instant unit translation.
-

Examples
-
2 pound foot/square second equals 276509908752000000 attonewton [aN].
-
0.5 pound foot/square second equals 69127477188000000 attonewton [aN].
Common Use Cases
-
Converting legacy FPS mechanical forces to SI units for modern scientific research.
-
Translating forces from classical mechanics problems for atomic-scale analysis.
-
Supporting development and calibration of ultra-sensitive force sensors like nanotube devices.
Tips & Best Practices
-
Always verify unit consistency when working with FPS-based forces.
-
Use this tool when needing high precision in converting to very small SI force units.
-
Be cautious with large numerical outputs to maintain computational accuracy.
Limitations
-
Pound foot/square second units are considered outdated for current applications.
-
Attonewton values represent forces too small for everyday mechanical scenarios.
-
Large numeric conversion values require careful handling to avoid rounding errors.
Frequently Asked Questions
-
What does pound foot per square second measure?
-
It measures force in the FPS system, equivalent to the force needed to accelerate a 1 lbm mass at 1 ft/s², also known as the poundal.
-
When should I use attonewton [aN] units?
-
Attonewton is used to express extremely small forces at atomic and sub-atomic scales, such as in molecular physics or ultra-sensitive sensor calibrations.
-
Why convert poundal to attonewton?
-
Converting from poundal to attonewton helps translate legacy imperial force values into precise SI units for modern scientific measurements.
Key Terminology
-
Pound foot/square second
-
A force unit in the FPS system equivalent to accelerating a 1 lbm mass by 1 ft/s²; also called the poundal.
-
Attonewton [aN]
-
An SI force unit equal to 10⁻¹⁸ newtons, representing extremely small forces at atomic and sub-atomic scales.
